Description

In SecPublicInfoSqlite3, the type of key is already saved along with the key DER. This allows it to distinguish an RSA key from another public key algorithm such as elliptic curve.

https://github.com/named-data/ndn-cxx/blob/c169a81a5caf3cb4dc14a0258719bc1ef09663cc/src/security/sec-public-info-sqlite3.cpp#L295

It seems that the SecPublicInfo API needs to have getPublicKeyType(keyName) so that KeyChain::sign can use the keyName do determine whether to create a SignatureSha256WithRsa or other type of signature.

Given the updated implementation of the PublicKey abstraction, this method is unnecessary and this issue should be rejected.

If I remember correctly, when one signs, it needs to get hold of (at least internally in keychain) of (Identity)Certificate, which encapsulates PublicKey. From PublicKey, the type can be retrieved directly, without requiring any new methods in SecPublicInfo.
