Σύνοψη	The Secure Hash Algorithm (SHA) is a family of cryptographic hash functions standardized by NIST starting in 1993. SHA functions produce fixed-length digests from arbitrary-length input data, serving as a fundamental building block for digital signatures, message authentication, and data integrity verification across security-critical applications.	The Transport Layer Security (TLS) protocol is the cryptographic standard that secures web communication and email transmission. Evolved from SSL (Secure Sockets Layer), TLS provides authentication, encryption, and integrity protection for data in transit. The protocol combines public-key cryptography (RSA, ECDH) for key agreement, symmetric encryption (AES) for bulk data, and digital signatures (SHA-256) for authentication.
