About Hash Functions

Cryptographic hash functions generate fixed-size digests from input data:

🔐 SHA-256

256-bit hash, part of SHA-2 family. Widely used in SSL, Bitcoin, and file integrity checks

🔑 SHA-512

512-bit hash for maximum security. Commonly used in security-critical applications

🔒 SHA-1

160-bit hash. Deprecated for security but still used for checksums and Git commits

🔓 MD5

128-bit hash. Broken for security but still used for file integrity verification

Encoding and Data Utilities

Encode, decode, measure sizes, and transform common formats.
