PigPGP 0.2.0512-bit RSA Cryptosystem on JavaScript
PigPGP 0.2.0PigPGP 0.2.0 is a Unicode-based, click-to-run RSA implementation on JavaScript (Netscape 4.06 or higher; IE 5.5 or higher). PigPGP is somewhat PGP-like, but not compatible with PGP/GPG.
The maximum supported key length is 512 bits. It runs quite fast for 128 bits (or 39 digits), which can be interesting for educational purposes, though being too weak for serious use. 256-bit system is not very strong either, but usable at a decent speed and good enough for some purposes. 360 and 512 bits are stronger and slower. Even 1024 bits would be possible, though not supported in this demo, as it would be VERY slow (like 30 minutes for key generation, a few minutes for decryption; encryption would be quite fast even for 1024 bits.)
Some of you may feel it thrilling enough just to see 512-bit RSA running on JavaScript. The main reason I wrote these codes is to enjoy myself, not that I thought RSA on JavaScript would be useful for practical purposes.
