This draft PR adds a new PKCS#1 v1.5 implicit rejection decryption API based on:
Issue #626
The new PKCS#1 v1.5 unpadding function does not return an error if the padding is invalid.
Instead, it deterministically generates and returns a replacement random message derived from the secret key and the ciphertext.
As a result, callers cannot distinguish between valid and invalid padding based on the output, thus reducing the risk side-channel attacks.
WARNING: This PR requires careful review before progressing beyond the draft stage.
