Are Electronic Signatures Secure?


Electronic signatures (Esignature) are a way to confirm an individual's agreement. They have been accepted and used in many countries all over the globe for years. Electronic signatures are now used by more than a billion people worldwide. Are electronic signatures legal?

Electronic signatures can be legal. This question is about whether electronic signatures can be used to create binding and enforceable contracts. The short answer to this question is "yes". In the industrialized world, electronic signatures are widely accepted. They are less susceptible to forgery than paper-based signatures.

This blog will explain what makes eSignatures legally binding and whether they are valid in the US. It will also discuss exceptions that exist and what an eSignature free is.

What's an Electronic Signature?

Digital signatures are an electronic way to verify the integrity and authenticity of digital documents or messages. It uses encryption to protect the authenticity of any message, document, or software. Digital signatures are a way to verify that the sender or author of a message is who they claim to be and that the content has not been altered.

Public key cryptography is a method that creates digital signatures. This system uses two keys to encrypt or decrypt information. The sender uses their key to encrypt the message or document and then sends the encrypted message and the public key. The sender then uses their public key to decrypt and compare the signature to the hash. The two hashes must match to confirm that the message or document has not been altered.

Digital signatures have one important characteristic: they can only be used on a specific message or document. Therefore, it will not be valid even if an attacker intercepts the message and attempts to use the digital signature in a different message or document.

There are many important uses for digital signatures. One of the most popular uses of digital signatures is for software signing. The digital signature of the publisher is used to sign the software distributed. This verifies that it has not been altered or comes from a trusted source. In addition, electronic transactions, such as online shopping, use digital signatures to protect sensitive information like credit card numbers.

Electronic documents are another important area where digital signatures can be used. Digital signatures can also be used in business to sign invoices and contracts. This allows you to verify that the document is original and has not been altered.

Digital signatures are an essential tool to ensure the integrity and authenticity of digital information. Individuals and organizations can use digital signatures to verify the identity and authenticity of the sender or author of a message, as well as to ensure that the content is not altered. Digital signatures will play an important role in securing electronic transactions and communications, given the growing use of digital information in every aspect of our lives.

What Are Different Types Of Electronic Signatures?

Digital signatures are essential tools for secure electronic transactions. There are many types of electronic signatures. Each has its strengths and weaknesses. Therefore, it is important to understand all options fully. These are the most popular types of electronic signatures.

Basic Electronic Signatures: This is the simplest type of electronic signature. It involves entering the signer's name in a document or using a simple digital signature tool that attaches a timestamp. Although simple electronic signatures can be created and used quickly, they are not legal and can easily be forged. This makes them ineligible for sensitive transactions.

Signatures with Biometrics: Signatures that use biological characteristics such as fingerprints or signatures to verify identity are called biometric signatures. Because the signer can only create biometric signatures, they are more secure than electronic signatures. Biometric signatures are more practical than others because they can be costly to implement and may be vulnerable to security breaches or technical failures.

Cryptographic Signs: Digital signatures use public key cryptography to ensure the authenticity of electronic signatures. Two keys are required to create a cryptographic signature. One key is used to encrypt, and one is used to decrypt. Because they aren't subject to the same security breaches or technical failures as biometric signatures and are, therefore, more secure than cryptographic signatures, they are less vulnerable to hackers. However, they can be complicated to set up and maintain and require specialized knowledge and expertise.

Qualified E-Signatures: Qualified digital signatures are a type of cryptographic signature certified by a trusted party to comply with certain technical and legal standards. Qualified  esignatures services can be legally binding in many countries, including the European Union, and offer high-level security and trust. However, they can be difficult to use and may require additional security measures to verify their validity.

Certificate-Based Digital Signatures: Qualified electronic signatures are very similar to digital signatures. They use public key cryptography and are certified through a trusted third party. Digital signatures based on certificates can only be used for certain applications such as software distribution or email. Qualified electronic signatures can be used for more transactions. Although digital signatures based upon a certificate are simple to use and offer high levels of security and trust, they may only be legally binding in some countries.

Signing Pads: Signing pads are physical devices that allow you to sign electronic documents with a stylus or your finger. Signage pads are used frequently in healthcare and retail environments. They provide high levels of security and trust as the signature can be verified in real-time. However, signature pads are expensive and can fail, so they may only be practical for some applications.

Secure electronic transactions can be made using electronic signatures. The specific transaction's requirements will determine the type of electronic signature used. This includes security, cost, legal requirements, and ease of use. To ensure the best possible solution for every situation, it is essential to fully understand the strengths and weaknesses of each type of electronic signature.

What are the Benefits of Electronic Signatures?

Electronic signatures (digital signatures) are a safe and easy way to sign and verify electronic documents. Electronic signatures have many benefits, including the following:


Electronic signatures make it possible to sign and verify documents from any location at any hour. For example, this allows individuals and businesses to sign and verify invoices and contracts from anywhere, at any time. It also reduces the time and cost associated with traditional paper-based signature processes.


An electronic signature is typically quicker than traditional paper-based signature processes. Electronic signatures can be signed electronically by the signer. They can be verified instantly by the recipient, which reduces the time it takes to complete a transaction.

Lower Costs

Electronic signatures may reduce costs associated with paper-based signature processes. This includes printing, postage, and courier fees. Electronic signatures are also more cost-effective than paper-based signature processes. All signed documents can be stored electronically and are easy to find.

Improved Security

Electronic Signatures use encryption to protect the integrity and authenticity of electronic documents. Electronic signatures are more secure than paper-based signatures because they can be tampered with and stored in a secure record.

Legal Validity

Electronic signatures can be legally binding in many countries, including the United States of America, Canada, and the European Union. Electronic signatures can be used for many transactions, including simple contracts and complex legal agreements.


Electronic signatures offer a more sustainable alternative to paper-based signatures. They eliminate the need for printing, paper, and courier services. In addition, electronic signatures are more sustainable than paper-based signatures, as they reduce the carbon footprint of individuals and businesses.


Individuals with disabilities can use electronic signatures to sign and verify important documents. For example, individuals with visual impairments can use screen readers and other assistive technology to sign and verify electronic documents.


Electronic signatures offer a secure and tamper-proof record that can be used to trace the signer and verify his signature's authenticity. This makes it easier for disputes to be resolved or to detect fraud.


You can audit electronic signatures to verify that they are valid, legal, and in compliance with applicable regulations and standards. This reduces the chance of fraud and ensures that electronic signatures are reliable and secure.

Electronic signatures are a convenient and secure way to free esign and verify electronic documents. Electronic signatures have many advantages: speed, convenience, lower costs, better security, the legal validity and environmental sustainability, accessibility, traceability, auditability, and increased speed. Electronic signatures are becoming more popular due to the numerous benefits they provide and the increased use of electronic documents throughout our lives.

What makes an electronic signature legally binding?

In 2000, the U.S. Federal Government passed the Electronic Signatures in Global Commerce Act. The Uniform Electronic Transactions Act (UETA) and this Act confirm that electronic signatures can be legally binding documents if they are signed digitally.

E-signatures encompass all technologies and solutions that allow you to sign documents electronically. These can be simple images or PKI-based signatures. There are many capture options available, including:

  • Clicking on "I Agree!" to go to a website
  • Signing with your finger using a mobile device
  • Online forms require you to enter your PIN or name
  • Using an eSignature solution such as eSignly eSignature

Are electronic signatures valid in all states?

Yes, electronic signatures are legal in all 50 states. They have the same legal status as handwritten signatures. Electronic signatures can also be used in all industrialized nations. They are as efficient and legal as handwritten signatures. While laws can vary between countries, you can learn more about your country's legal requirements by visiting eSignature's eSignature Legality Guide.

A legally enforceable document requires an electronic signature, such as the one provided by eSignly eSignature. Additional authentication may be necessary for certain situations in the United States. Digital signatures can also be made using tools like eSignly standards-based signs. Digital signatures are more common in Europe and other regions.

Are Electronic Signatures Legally Enforceable?

Combining eSignatures with solid authentication, tamper sealing, and audit trails can provide stronger court-admissible evidence than a simple wet image or scan of a signature on a PDF.

The validity of wet signatures is often established by comparing signatures or providing testimony from handwriting experts and witnesses. This can be time-consuming and costly, making the process less reliable due to the human element. Audit trails reduce human error and automate data capture. This makes verifying signature authenticity easy and resolving disputes in federal and state courts.

Tyler Newby, Partner, Fenwick & West LLP, does an outstanding job describing how important audit trails are for authenticating eSignatures in court. He writes in his article "Using E-Signatures In Court--The Value Of an Audit Trail."

DocuSign eSignature generates and stores a time-stamped history for each send, view, print, or sign action for every document. In addition, the system maintains information about the signer, the signing date, and the documents in what we call a "Certificate of Completion." The Certificate of Completion includes a summary of the signing event and an envelope.

  • An Envelope ID
  • The identity of the sender
  • The identity of the signer(s).
  • An illustration of their signatures
  • Date and time stamps of when the document was sent, viewed, and signed
  • The IP address at which each of these actions occurred

Are Digital Dignatures Secure?

The use of digital signatures is widely accepted as a secure way to verify the integrity and authenticity of electronic documents and transactions. As a result, they are used across many industries, including finance and healthcare, to verify the authenticity of sensitive information.

Digital signatures are created using encryption and public key infrastructure technology (PKI). A unique code is generated when a document has been signed. It is based on the contents and the private keys of the signer. This code (or signature) is then added to a document and sent to its recipient.

The recipient will verify their signature when they receive the signed document. The valid signature confirms that the document was not altered during transit and comes from the signer. This is a way to verify the integrity and authenticity of the document. In addition, it makes it less likely that an attacker would manipulate the information for malicious purposes.

Digital signatures can be used to confirm authenticity and integrity. They also offer non-repudiation. Digital signatures can prove that the signer has signed the document.

Digital signatures are secure due to several factors. First, digital signatures are protected by strong encryption algorithms such as RSA (or Elliptic Curve Digital Signature Algorithm), which have been extensively tested and validated.

Second, digital signatures can be used with PKI to verify the authenticity of public key keys and protect against malicious actors trying to impersonate trusted signers. Finally, PKI provides a secure infrastructure to manage and exchange public keys. This reduces the risk of unauthorized access or tampering.

Digital signatures are thirdly dependent on a trusted and secure infrastructure. For example, a secure digital certification authority is needed to issue and manage digital certs. This allows for the verification of the signer and ensures that the system is safe from hackers.

Digital signatures can also be used with additional security measures, such as multi-factor authentication or secure socket layers (SSLs), to increase the security of electronic transactions.

Digital signatures can verify the authenticity and integrity of electronic documents and transactions. Strong encryption algorithms, PKI, and secure infrastructure are all used to protect digital signatures. This also reduces the chance of malicious attacks. While not completely secure, digital signatures are used widely in many industries because they provide high levels of security.

What are Some of the Potential Risks Associated with Electronic Signatures?

Digital signatures are generally more secure than traditional wet-ink signatures, particularly if generated using a particular digital signature software. The digital signature software platforms and products also use encryption and cryptography technology along with public key infrastructure (PKI), which adds a step to authentication intended to prevent tampering.

However, organizations still need to consider risks when implementing electronic signatures.

Reliability and risk of Fraud

While a dedicated digital signing platform can solve all authentication issues in the e-signing process, there is still a high chance of signatory forging or fraud for organizations, as technology can be compromised. You can take additional measures to combat this, such as obtaining an authentication confirmation by phone.

Unauthorized Signing

This is a serious problem with electronic and wet ink signatures. How can organizations ensure that all signatories, including e-signatories, are properly authorized? How can organizations ensure that all their signatories (incl. e-signatories) are properly authorized? How can signatories find out what they are authorized to sign? Blockchain technology allows organizations to securely and efficiently manage signatory lists in real-time and maintain a clear audit trail of any data changes.


Organizations should comply with all applicable regulations and rules for the presentation of documents, disclosures, and other information during transactions (e.g., MiFID, FCA). Failure to comply with regulations can lead to organizations being sanctioned, fined, losing their accreditation, or affecting their brand equity.

The Key Takeaway

It is not your intention to have your customers' esignatures rejected. These are the best practices to avoid this:

  • Ensure that the audit trail backing up your signature's validity is clear. This includes any actions taken by the signator before they sign the document. For example, they have clicked Next Page to sign or check a box to confirm that they have agreed to the terms.
  • Securely sign on to a site using user authentication.
  • Third-party software can be used to confirm that you have complied with disclosure requirements.
  • A third party can be used to secure a storage location that will ensure that the document cannot be altered after it is signed.
  • Provide an easy way for signers to download and save a duplicate of the document.
