Hash Generator & Lookup
MD5, SHA-256, bcrypt hash generation and rainbow table lookup
MD5 Hash Generator
Generate MD5 hashes from text in real time. Instant output, uppercase toggle, 100% browser-based. Not for passwords — use bcrypt instead.
MD5 Decrypt — Hash Lookup
Reverse-lookup MD5 hashes via rainbow table databases. Not true decryption — MD5 is one-way. Checks multiple sources for the best match rate.
SHA-256 Hash Generator
Generate SHA-256 hashes from text instantly. WebCrypto hardware-accelerated, real-time output. Used in Bitcoin, TLS, and digital signatures. Zero uploads.
SHA-256 Decrypt — Hash Lookup
Look up SHA-256 hashes against rainbow table databases. Not true decryption — SHA-256 is one-way. Works only for common, previously indexed strings.
Bcrypt Hash Generator
Generate bcrypt hashes with configurable cost factor (4–31). Auto-salted, rainbow-table resistant, fully browser-based. Recommended for secure password storage.
Bcrypt Hash Verifier
Verify a password against a bcrypt hash instantly in your browser. Supports $2a$, $2b$, and $2y$ prefixes. Nothing is uploaded.
Generate cryptographic hashes using MD5, SHA-1, SHA-256, bcrypt, and other industry-standard algorithms. Verify file integrity, check password hashes against known breach databases with k-anonymity, and generate salted hashes for secure password storage. All hashing and lookups are performed locally in your browser for maximum privacy.
