SHA512 Hash

Generate 512-bit SHA512 hash from text

About SHA512 Hash

SHA-512 (Secure Hash Algorithm 512-bit) is part of the SHA-2 family and produces a 512-bit (128 hexadecimal characters) hash value. It offers the highest security level in the SHA-2 family.

Output length: 128 characters (512 bits)

Use cases: Maximum security applications, digital forensics, high-value data protection

Security note: Maximum security, suitable for the most critical applications

Hash Properties

Deterministic: Same input always produces same output
Fixed Length: Output size is always constant
One-way: Cannot reverse hash to get original input
Avalanche Effect: Small input change = big hash change
Fast Computation: Quick to calculate
Collision Resistant: Hard to find two inputs with same hash

Security Notice

  • • Hashes are not encryption - they cannot be reversed
  • • For password storage, use proper password hashing functions (bcrypt, scrypt, Argon2)
  • • Always use salt when hashing passwords or sensitive data
  • • MD5 and SHA-1 are not recommended for security-critical applications
  • • All processing is done locally - no data is sent to our servers
