About

This extension is used to compute cryptographic hashes and do common conversions. It might be useful for programmers and system administrators. It's entirely implemented in JavaScript, all calculations are performed on client side, so it's safe.

• Hash: MD5, SHA-1, SHA-2 (224, 256, 384, 512), RIPEMD-160, MD4, Whirpool
• 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

Usage: enter text and click on the result. It will be copied to clipboard.

Extension is using crypto-js and other open-source libraries.
