Algorithm;
Key size;
Parameters Specification (for Elliptic Curve keys);
ASN.1 representation;
Fields, depending on the Algorithm type:
Fields of RSA Public Key: Modulus, Public Exponent.
Fields of DSA Public Key: Base Generator G, Prime Modulus P, SubPrime Q, Public Key.
Fields of EC/ECGOST3410 Public Key: Public Point Affine X-coordinate, Public Point Affine Y-coordinate, Cofactor, First Coefficient A, Second Coefficient B, Finite Field Size, Generator Affine X-coordinate, Generator Affine Y-coordinate, Generate Order.
