Understanding the Digital Signature Algorithm (DSA) in Cryptography 🔐

The Digital Signature Algorithm (DSA) is an Asymmetric Encryption algorithm... but it's different from the other Asymmetric Encryption algorithms we've discussed (RSA & DH). DSA has only two functions: Signature Generation and Signature Verification. It cannot do Encryption, it cannot do Decryption, it cannot do a Key Exchange. It's use is purely creating and verifying Signatures, which provides Integrity and Authentication to what is signed.

This lesson is a free sample lesson from the the greatest TLS and SSL training course ever created. No instructor rambling on about pointless stories. No slides with massive walls of text. No time wasting. Only simple, effective, and precise explanations. Complimented with practical illustrations and visuals.
