	// Returns the signature as a byte slice or an error if signing fails.

	// Returns true if the signature is valid, false otherwise, along with any error encountered.

	// Encrypt encrypts the given data and returns the encrypted result as a byte slice.
	// Returns an error if encryption fails.

	// Decrypt decrypts the given encrypted data and returns the original data as a byte slice.
	// Returns an error if decryption fails.
	Decrypt(data []byte) ([]byte, error)

	// EncryptBase64 encrypts the given data and encodes the result as a base64 string.
	// Returns the base64-encoded encrypted string or an error if encryption fails.

	// DecryptBase64 decodes the given base64-encoded string and decrypts it.
	// Returns the original data as a byte slice or an error if decryption fails.
