Unreasonably Strong Cryptography, by Ruptor


The only version of PGP I trust more or less: 6.5.8 CKT. Stick to RSA-8192 + Tiger-192 + Twofish-256! Standard Diffie-Hellman and ECC Diffie-Hellman algorithms may be based on backdoored primes.

Ruptor's famous Crypto.Lib - The fastest on Earth (faster than MIRACL) minimalistic implementation of all the necessary cryptographic primitives including authenticated ECDH-512 in pure C is almost there.

Secure Telephone for private sector called Cryptofone (based on Ruptor's Crypto.Lib)

Freeware IRC encryption called PureNoise (based on Ruptor's Crypto.Lib) - Just ignore all the bs text on that site; MSN, ICQ, AIM, YM and Skype support are coming soon too.

Ruptor's WARNING:
Trillian has easily breakable 128-bit Diffie-Hellman key exchange in it. Do not trust the built-in Trillian encryption!!!

PureNoise for Trillian strong encryption plug-in v2.5 - Updated 23.05.2004

128-bit Diffie-Hellman over a random 128-bit prime is replaced with 512-bit Elliptic Curve Diffie-Hellman (over SSC-512)

128-bit BFC Blowfish is replaced with 256-bit Twofish with non-linear block chaining.

It's not a perfect implementation, but it's something. Simply replace the original Trillian crypto.dll with mine. The password to the source RAR is PureNoiseLtdVaduz, and ignore the padlock saying it's 128-bit. It's lying! ;-) It's 256-bit now.

Remember, RSA or DH/DSS keys are only as strong as about twice the cubic root of their length comparing to symmetric keys, and Elliptic Curve keys are as strong as half their length. The table below shows approximate complexity of the fastest known algorithms solving DLP or factoring numbers of a given length thus breaking DH or RSA:
  512 -> 2^32
 1024 -> 2^40
 2048 -> 2^48
 4096 -> 2^64
 8192 -> 2^80
16384 -> 2^100
 Common HASH functions turned into block ciphers by Ruptor... kinda reversible, aren't they?

More Ruptor's stuff - Symantec should have checked there years ago, they wouldn't screw up with the [l]sasser virus so bad. Some archives there may be broken, will fix them later.
