(Not yet released) Diffie-Hellman key-exchange component.

Diffie-Hellman (D-H) key exchange is a cryptographic protocol that allows two parties that have no prior knowledge of each other to jointly establish a shared secret key over an insecure communications channel. This key can then be used to encrypt subsequent communications using a symmetric key cipher.

Synonyms of Diffie-Hellman key exchange include:

• Diffie-Hellman key agreement
• Diffie-Hellman key establishment
• Diffie-Hellman key negotiation
• exponential key exchange
