Digital signature is a powerful tool for ensuring the authenticity, integrity, and confidentiality of electronic documents. Class 3 digital signature tokens provide the highest level of security and are used for applications that require a high level of trust, such as e-commerce transactions, financial transactions, and legal contracts.

There are two types of Class 3 digital signature tokens: with signing and with signing and encryption. In this blog, we will discuss both types of tokens and their uses.

Class 3 Digital Signature Token with Signing

Class 3 digital signature tokens with signing provide the highest level of security for electronic signatures. They are used to sign electronic documents and ensure the authenticity and integrity of the document.

The process of signing a document using a Class 3 digital signature token with signing involves the following steps:

1. The user inserts the token into the computer and enters the password to unlock it.
2. The user selects the document to be signed.
3. The document is hashed using a cryptographic algorithm to create a unique digital fingerprint of the document.
4. The digital fingerprint is encrypted using the private key stored in the token.
5. The encrypted digital fingerprint, along with the public key of the signer, is attached to the document to create the digital signature.
6. The signed document is sent to the recipient, who can verify the authenticity and integrity of the signature using the public key of the signer.

Class 3 Digital Signature Token with Signing and Encryption

Class 3 digital signature tokens with signing and encryption provide the highest level of security for electronic signatures and encryption. They are used to sign and encrypt electronic documents to ensure both authenticity, integrity, and confidentiality.

The process of signing and encrypting a document using a Class 3 digital signature token with signing and encryption involves the following steps:

1. The user inserts the token into the computer and enters the password to unlock it.
2. The user selects the document to be signed and encrypted.
3. The document is hashed using a cryptographic algorithm to create a unique digital fingerprint of the document.
4. The digital fingerprint is encrypted using the private key stored in the token.
5. The encrypted digital fingerprint, along with the public key of the signer, is attached to the document to create the digital signature.
6. The document is encrypted using the public key of the recipient.
7. The signed and encrypted document is sent to the recipient, who can decrypt the document using their private key and verify the authenticity and integrity of the signature using the public key of the signer.

Conclusion

Class 3 digital signature tokens with signing and with signing and encryption provide the highest level of security for electronic signatures. They are used for applications that require a high level of trust, such as e-commerce transactions, financial transactions, and legal contracts. By using these tokens, organizations can ensure the authenticity, integrity, and confidentiality of electronic documents, thereby improving their security and reducing the risk of fraud and cyber attacks.
