Cryptographic Hashing Guarantees
All hashes are computed locally using your browser's native Web Crypto API (SubtleCrypto) and standard client-side algorithms. No text or passwords ever leave your machine.
Supported Algorithms
MD5 and SHA-1 are legacy checksums with known collision weaknesses; do not use them for password storage or adversarial integrity checks. Maximum text input: 1 MiB.
- SHA-256: Standard industry hash for data integrity, blockchain, and digital signatures.
- SHA-512: High-security 512-bit digest ideal for cryptographic verification.
- SHA-1: 160-bit legacy digest commonly used for Git commit hashing and archive integrity.
- MD5: 128-bit checksum widely used for verifying download file integrity.
