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 ↔ Hex, Ip ↔ Bin
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.
It's possible to open extension in separate window.
