WebbThis algorithm is based on RSA PKCS #1, which is still the most widely used standard for public / private key cryptography. Any decent JWT library should support it. RSxxx signatures also take very little CPU time to verify (good for ensuring quick processing of access tokens at resource servers). 2048 bits is the recommended RSA key length. Webb4 nov. 2024 · RSA certificates always support all hash algorithms (and this has nothing to do with the algorithm that was used when the certificate itself was signed – an RSA certificate carrying a SHA1 signature from the CA can still generate SHA256 or SHA384 signatures itself, though all such certificates should have already expired by now). I …

WebbThe RSA algorithm uses keys of size 1024, 2048, 4096, ..., 16384 bits.
