A Firefox-friendly fork of https://github.com/s12v/hasher
99% of the credit goes to the original developer; I liked it so much I "ported" it to a WebExtension when I switched back to Firefox.
The extension is used to compute cryptographic hashes and perform conversions. It is useful for programmers and system administrators. The extension is implemented in JavaScript. All calculations are performed on the client side.
- Hash: MD5, SHA-1, SHA-2 (224, 256, 384, 512), SHA-3, RIPEMD-160, MD4, Whirlpool
- HMAC: MD5, SHA-1, SHA-2 (224, 256, 384, 512), RIPEMD-160, MD4
- CRC: CRC-8, CRC-16, FCS-16, FCS/CRC-32
- Cipher (interoperable with OpenSSL): AES-256, DES, Triple DES, Rabbit, RC4, RC4Drop. CBC/Pkcs7 is used.
- Net: Subnet calculator, Ip ↔ Dec, Ip → Bin, Ip → Hex
- Time: Unix ↔ Datetime, Unix ↔ RFC-1123, Unix ↔ ISO 8601
- Numbers: Dec ↔ Hex, Dec ↔ Bin, Dec ↔ Roman
- Strings: ASCII ↔ Hex, UTF-8 ↔ Hex, UTF-16 ↔ Hex
- Encode: Base64, ROT-13, JavaScript encodeURI(), encodeURIComponent(), HTML special chars encode/decode
