verify_ecdsa_signature_auto_recovery

Verify a Bitcoin ECDSA signature with automatic y_parity detection

This function tries both y_parity values (false and true) to find a match with the provided public key. This is useful when the y_parity is unknown or when working with DER signatures that don’t include recovery information.

Arguments

• message_hash - The hash of the message that was signed
• r - The r component of the signature
• s - The s component of the signature
• public_key - The public key to verify against

Returns

• bool - True if signature is valid with either y_parity value
