RSA Algorithm Definition and Examples

Understanding the RSA Algorithm for e-Signing

When it comes to e-signing, security is paramount—enter the RSA algorithm. But what exactly is the RSA algorithm, and why is it essential for electronic signatures? Let's dig into it.

RSA Algorithm stands for Rivest-Shamir-Adleman algorithm, named after its inventors. It's a cryptographic algorithm used to secure data transmission. This algorithm is pivotal for ensuring the integrity, authenticity, and non-repudiation of e-signatures.

What is the RSA Algorithm?

The RSA algorithm is a form of public key cryptography, utilizing two keys: a public key, which can be shared openly, and a private key, kept secret by the owner. Here's a basic rundown:

1. Key Generation:

   • Two large prime numbers are chosen and multiplied to generate a key pair.
   • The resulting product and an auxiliary value are used to produce the public and private keys.

2. Encryption:

   • Data encrypted with the public key can only be decrypted using the corresponding private key. This ensures that only the intended recipient, who possesses the private key, can access the encrypted information.

3. Decryption:

   • Conversely, data encrypted with the private key can be decrypted by anyone with the public key. This is useful for verifying the sender's identity since it proves that the message could only come from the holder of the private key.

Examples of RSA Algorithm in Action for e-Signing

1. Digital Signatures:

   • When you send a document via an e-signature service like GoodSign, the RSA algorithm helps create a digital signature unique to that document. This digital signature, encrypted with your private key, can be verified by anyone using your public key. This verifies that the document hasn’t been altered since the signature was applied.

2. Secure Document Transmission:

   • RSA encryption ensures that documents sent and signed electronically remain confidential and secure. Only the intended recipient can decrypt and access the document, providing peace of mind that sensitive information remains protected.

3. Authentication and Integrity:

   • RSA’s digital signatures authenticate the sender and ensure the document’s integrity. In other words, recipients can be confident that the document is genuinely from the sender and hasn’t been tampered with during transit.
