SHA-512 (Secure Hash Algorithm 512-bit) is a cryptographic hash function that takes an input and produces a 512-bit (64-byte) hash value. This hash is typically rendered as a 128-digit hexadecimal number.
Key characteristics of SHA-512:
- Always produces a fixed-size output (512 bits)
- Same input always yields the same hash
- Small changes in input result in vastly different hashes
- One-way function (cannot derive original input from hash)
- Highly collision-resistant
Security Note: SHA-512 offers even stronger security than SHA-256, making it suitable for high-security applications and future-proofing against potential advances in cryptographic attacks.
- High-Security Applications: Used where maximum security is required, such as government and military systems
- Digital Signatures: Used in advanced digital signature schemes requiring maximum security
- Password Storage: Securing highly sensitive credentials with stronger protection than SHA-256
- Data Integrity: Verifying integrity of large files and critical data where maximum collision resistance is required
Example SHA-512 hash:

Advantage of SHA-512 over other hash functions:
SHA-512 is part of the SHA-2 family designed by the NSA, offering the highest security level in the family. With a 512-bit output, it provides twice the bit-length of SHA-256, making it significantly more resistant to collision and preimage attacks. It's particularly beneficial for 64-bit systems where it can actually be faster than SHA-256 in some implementations. SHA-512 is recommended for applications requiring maximum security and long-term protection against future cryptographic advances.
