Detailed Description

ElGamal key agreement and encryption schemes keys.

ElGamalKeys provide the algorithm implementation ElGamal key agreement and encryption schemes.

The ElGamalKeys class used DL_PrivateKey_GFP_OldFormat and DL_PublicKey_GFP_OldFormat for the PrivateKey and PublicKey from about Crypto++ 1.0 through Crypto++ 5.6.5. At Crypto++ 6.0 the serialization format was cutover to standard PKCS8 and X509 encodings.

The ElGamalKeys class [mistakenly] used the OID for DSA from about Crypto++ 1.0 through Crypto++ 8.2. At Crypto++ 8.3 the OID was fixed and now uses ElGamal encryption, which is 1.3.14.7.2.1.1. If you need to Load an ElGamal key with the wrong OID then see ElGamal on the Crypto++ wiki.
