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
