What is a Digital Signature?
A digital signature is a cryptographic technique used to validate the authenticity and integrity of a digital message, document, or software. It provides a unique identifier that verifies the signer's identity and ensures that the content has not been altered since it was signed.
How Does Digital Signature for Invoice Signing Work?
When a digital signature is applied to an invoice, it involves a series of steps to ensure security and authenticity:
Hashing: The content of the invoice is converted into a unique digital fingerprint called a hash. This hash is unique to the specific content and any change in the content will result in a different hash.
Encryption: The hash is encrypted using the signer's private key, creating the digital signature. The private key is known only to the signer and is used to encrypt the hash, ensuring that only the signer can create the signature.
Verification: To verify the signature, the recipient uses the signer's public key to decrypt the signature and obtain the hash. The recipient then hashes the received content and compares it with the decrypted hash. If the two hashes match, the signature is valid, and the content is considered authentic and unaltered.
