WebYou cannot encrypt anything with RSA which is larger than the key size (minus some padding and header) which means that you cannot sign anything if the signature algorithms results in a value larger than the key. A hash digest is 256 bit for SHA-256 or 192 bit for (already insecure) SHA-1, i.e. way larger than 32 bit.
