These algorithms utilize a pair of keys: a private key for signing and a public key for verification.
The process involves hashing the message content with a cryptographic hash function, such as SHA-256, to create a fixed-length digest. This digest is then encrypted with the signer’s private key using the chosen encryption algorithm, producing the digital signature. The recipient can verify the signature by decrypting it with the signer’s public key and comparing the result to a freshly computed hash of the original message.
Key management and the choice of encryption algorithms are critical to digital signature security. Proper implementation ensures compliance with legal standards and protects against vulnerabilities inherent in weaker or outdated cryptographic methods.
