These offer about the same security as a symmetric encryption algorithm with 112 bits of security.
WebMay 1, 2024 · How does Diffie-Hellman work? Diffie-Hellman is what's called a key exchange protocol. This is the primary use for Diffie-Hellman, though it could be used for encryption as well (it typically isn't, because it's more efficient to use D-H to exchange keys, then switch to a (significantly faster) symmetric encryption for data transmission).

WebDec 17, 2014 · First and foremost, the javascript library you mention implements RSA, which is asymmetric encryption. Diffie-Hellman is a key sharing scheme that uses asymmetric encryption to share a secret key which is then used for symmetric encryption. You're not avoiding asymmetric encryption with either of those suggestions. The Diffie–Hellman key exchange method allows two parties that have no prior knowledge of each other to jointly establish a shared secret key over an insecure channel. This key can then be used to encrypt subsequent communications using a symmetric-key cipher. Diffie–Hellman is used to secure a variety … See more Diffie–Hellman key exchange is a mathematical method of securely exchanging cryptographic keys over a public channel and was one of the first public-key protocols as conceived by Ralph Merkle and … See more General overview Diffie–Hellman key exchange establishes a shared secret between two parties that can be used for … See more Diffie–Hellman key agreement is not limited to negotiating a key shared by only two participants.
