Create Signature (Deterministic) (secp256k1)

Signs the given hash deterministically with the private key using secp256k1, returns a signature.

Requires the given hash to be at least 16 bytes in length. Too short and it will fail. Too long and the
overflowing bytes will be cut off.

Inputs

In Exec
Private Key Array of Bytes	The private key to use for signing.
Hash Array of Bytes	The hash to sign.
Digest Type Ecdsa EWeb3S_DigestTypeEcdsa Enum	Type of the hash function used in hashing the message.

Outputs

Out Exec
Signature Array of Bytes	The created signature.
Success Boolean	False on failure.
