Hasher

Developer's toolbox. Calculates MD5, SHA-1, SHA-2, IP/Subnet, URL decode, Base64 and more

What is Hasher?

Hasher is a Chrome extension that provides a developer's toolbox for calculating cryptographic hashes, performing common conversions, and assisting programmers and system administrators. It offers various hash algorithms, HMAC, CRC calculations, ciphers, network tools, time conversions, number conversions, string manipulations, and encoding options. All computations are done locally and the extension is safe to use. Source code is available on github.

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:

Very nice toolbox!

This is a great tool, really quick and useful. It would be great if there was an option to configure which hasher I want to be visible. For example, I'm only interested in the MD5 and url-encoder.
