RSA refers to both a signature algorithm (a cryptographic operation) and an encryption key pair. The RSA algorithm is used to generate an RSA key pair that includes both private and public keys. The first generates digital signatures, whereas the second verifies those created signatures. The algorithm used to generate the key pairs. The default is RSA. keysize: Specifies the size in bits to use when generating the cryptographic keys used to create the certificate. The larger the key size, the harder it is to break the encryption; however, the time to decrypt encrypted data increases with key size.
May 30, 2020 · Before we see how to generate JWT token with Private/Public key, let us see how to generate a Private and Public RSA Key pairs. 6.1 Generate Private and Public RSA Key. Generate an RSA private key, of size 2048, and output it to a file named key.pem:
