It's entirely implemented in JavaScript, all calculations are performed on client side, so it's safe. It is Firefox port of original chrome extenion by Sergey Novikov.

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
