```
 abstract void verify(@NotNull() Array<byte> originalData, @NotNull() DigitalSignature signature, @NotNull() PublicKey publicKey, @NotNull() SignatureSpec signatureSpec)
```
    Verifies a digital signature against data. Throws CryptoSignatureException if verification fails.
    
    Parameters:
    
    originalData - The original data on which the signature was applied (usually the Merkle root).
    
    signature - The digital signature.
    
    publicKey - The signer's PublicKey.
    
    signatureSpec - The signature spec.
