About SHA-512
- • SHA-512 (Secure Hash Algorithm 512-bit) is a cryptographic hash function
- • Produces a 512-bit (64-byte) hash value, typically rendered as 128 hexadecimal digits
- • Part of the SHA-2 family, designed by the NSA and published by NIST
- • One-way function: impossible to reverse the hash back to original data
- • Deterministic: same input always produces the same hash
- • Avalanche effect: small input changes produce completely different hashes
- • More secure than SHA-256 due to larger output size
Common Uses:
- • Password storage (when properly salted)
- • File integrity verification
- • Digital signatures and certificates
- • Blockchain applications requiring higher security
- • Cryptographic key derivation
- • Data deduplication
- • Software integrity checks
SHA-512 vs SHA-256:
- • SHA-512 produces 512-bit output vs SHA-256's 256-bit
- • SHA-512 is faster on 64-bit systems, slower on 32-bit
- • Both are considered cryptographically secure
- • SHA-512 offers slightly better collision resistance
Security Note:
SHA-512 is considered cryptographically secure for most applications. However, for password hashing, use specialized algorithms like bcrypt, scrypt, or Argon2 that are designed to be slow and resist brute-force attacks.
