| Resumo≠ | 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. | RSA (Rivest–Shamir–Adleman) is a foundational asymmetric cryptosystem introduced in 1978 that enables both encryption and digital signatures using a pair of public and private keys. It remains one of the most widely deployed cryptographic algorithms in modern security infrastructure, supporting secure communication and authentication across the internet. |
