I have produced a signing certificate with DSA keys, and it has the following field which made me curious:
Public Key Algorithm: dsaEncryption
AFAIK, DSA is not suitable for encryption. Then what does this stand for? Did they mean ElGamal encryption or what? I spent more than an hour searching in specifications, etc., still I don't know.
It is particularly interesting that if a certificate like this is fed to the openssl function EVP_PKEY_encrypt_old(), then it works (doesn't fail). I found this interesting, because in the source code I found, they only handle RSA encryption.
What is going on here?
Any help would be appriciated.
