what encryption is used?

Why type of Encryption that usually used in sending an e-mail, and login password on website?

  • i'm doing a research on encryption/decryption techniques, comparison the most commonly used crypthography & wanted to find some information that might help... Thanking in Forward

  • Answer:

    As in the previous answer, the most commonly used encryption for websites is SSL. For email, there are many options. The lack of a common standard is probably one of the prime reasons that more email is not encrypted. Here is a very short list of some of the most commonly used terms in this space: *PGP *PKI (public key infrastructure) *identity-based encryption (www.voltagesecurity.com) *Diffie-Hellman Key Exchange (see also RSA) *Blowfish Algorithm Check out Bruce Schneier's website and books (http://www.schneier.com). Bruce knows just about everything there is to know about encryption (see "Practical Cryptography").
