Processing happens locally in your browser. Input is limited to 2 MB.

Browser-localYour text stays on your device. Only anonymous usage metadata such as byte counts and processing time may be recorded.
Security labelsSHA-256 and modern SHA-2/SHA-3 hashes are preferred for general cryptographic hashing. MD5 and SHA-1 are clearly treated as legacy.
Not password hashingThis tool does not generate bcrypt or Argon2id password hashes. Password storage requires dedicated salted, slow password-hashing functions.

SHA-2 and SHA-3

Generate SHA-224, SHA-256, SHA-384, SHA-512 and SHA3-224/256/384/512 digests for modern hashing workflows.

Legacy compatibility

Generate MD5, SHA-1 and RIPEMD-160 when interoperating with older systems, while keeping their security limitations visible.

CRC32 checksum

Create a compact CRC32 checksum for accidental-corruption checks. CRC32 is not a cryptographic security hash.

Base64 Encoder / Decoder Encode UTF-8 text to Base64 or decode Base64 back to text directly in your browser, including Base64URL support. Advanced Password Generator Generate strong random passwords locally in your browser with configurable length, character groups and ambiguity filtering. Text / Code Diff Checker Compare two text or code versions line by line locally in your browser with added, removed, and unchanged line highlighting.
