Crypto Tool

Not very impressive, I know.
The Crypto Tool allows perfoming a couple of cryptographic and mathematic operations on byte arrays.
I made it a long time ago to understand and reproduce cryptographic operations of smart cards (mainly sample calculations in manuals). If you are new to cryptography, this tool may be helpful.
