Which Crypto Algorithm?

• Many ciphers can be used in cryptsetup: des, 3des, serpent, blowfish, twofish, aes, rot26, and 3rot26...

• blowfish was a good and fast option, but aes is now the standard, and linux has a fast i586 assembly version.

• You also get to pick your hashing function, and initialization vector...

• Ultimately, forget about everything else, and go with the current crypsetup default of “-c aes-cbc-essiv:sha256” (cbc being better than ecb, essiv being a good initialization vector, and sha256 a currently still good hashing algorithm)
