Encrypt with RSA public key private DKG share key.

GenerateRSAKeys creates a random RSA key pair.

GetNetworkByFork translates the network fork bytes into name TODO: once eth2_key_manager implements this we can get rid of it and support all networks ekm supports automatically.

ParseRSAPublicKey parses encoded to base64 x509 RSA public key.

RecoverBLSSignature recovers a BLS master signature from T-threshold partial signatures.

RecoverValidatorPublicKey recovers a BLS master public key (validator pub key) from provided partial pub keys.

SignRSA create a RSA signature for incoming bytes.

VerifyDepositData reconstructs and checks BLS signatures for ETH2 deposit message.

VerifyRSA verifies RSA signature for incoming message.

VerifySignedMessageByOwner returns nil if signature over message is valid (signed by owner).
