2.AES: 128 Bit Block – 128, 192, 256 Bit Key – 10, 12, 14 Rounds
3.BlowFish: 64 Bit Block – 32 thru 448 Bit Key – 16 Rounds
4.TwoFish: 128 Bit Block – 1 thru 256 Bit Key – 16 Rounds
5.Serpent: 128 Bit Block 128, 192, 256 Bit Key – 32 Rounds
6.SkipJack: 64 Bit Block – 80 Bit Key – 32 Rounds
7.IDEA: 64 Bit Block – 128 Bit Key – 8.5 Rounds
8.Symmetric Block Ciphers: DES – AES – BlowFish – TwoFish –
Serpent – SkipJack – IDEA
9.Symmetric Block Ciphers with 64 Bit Block Size: DES – BlowFish –
SkipJack<\/p>\n\n\n\n
Serpent
11.Symmetric Block Ciphers with 128, 192, 256 Bit Key Size: AES – Serpent
12.Symmetric Block Ciphers with 16 Rounds: DES – BlowFish – TwoFish
13.Symmetric Block Ciphers with 32 Rounds: Serpent – SkipJack
14.RC4: 1 thru 2048 Bit Key Size & 1 Round (40 bit minimum
recommended)
15.FISH: Uses Lagged Fibonacci pseudorandom number generator
16.PIKE: Revised version of FISH to address known plaintext attack
vulnerabilities
17.Symmetric Stream Ciphers: RC4 – Fish – Pike
18.Asymmetric Encryption Algos: RSA – ECC – El Gamal – DSA
19.RSA: Leverages prime number characteristics, 1024-4096 bit
variable key size, 1 round. Uses Trapdoor function to enable use for
encryption and digital signatures. One-way trapdoor functions can be
inverted with knowledge of trapdoor factorization information.
20.ECC: Leverages discrete logarithm characteristics
21.El Gamal: Used in recent versions of PGP<\/p>\n","protected":false},"excerpt":{"rendered":"
