A Review on Cryptography Using SHA Algorithm
Sejal Parab · INTERANTIONAL JOURNAL OF SCIENTIFIC RESEARCH IN ENGINEERING AND MANAGEMENT · 2025
Abstract: As digital technology continues to expand into every field, ensuring the integrity and authenticity of data has become increasingly essential. Cryptographic hash functions, especially the Secure Hash Algorithm (SHA) family, are instrumental in achieving these objectives. This review presents a detailed study of SHA-1, SHA-2, and SHA-3, discussing their algorithmic design, strengths, weaknesses, and applications in digital security. The paper provides comparative insights supported by research literature and explores recent advances in cryptanalysis and the challenges posed by quantum computing. Keywords: SHA, Cryptography, Hash Functions, SHA-1, SHA-2, SHA-3, Blockchain, Digital Signatures, Data Integrity, Post-Quantum Security
