Uses Trapdoor function to enable use for encryption and digital signatures. One-way trapdoor functions can be inverted with knowledge of trapdoor factorization information. ECC Leverages discrete logarithm characteristics El Gamal Used in recent versions of PGP DSA A Federal Information Processing Standard for digital signatures (FIPS 186) Hash Algos MD5 - SHA1 - SHA256 - FORK256 - RIPEMD160 - GOST - TIGER MD5 128 Bit Hash Value SHA1 160 Bit Hash Value SHA256 256 Bit Hash Value
