RSA Encryption and Decryption using Bouncy Castle Crypto APIs In cryptography, RSA (which stands for Rivest, Shamir and Adleman who first publicly described it) is an algorithm for public-key cryptography. I am using the Java Bouncy Castle provider to generate RSA key pairs. I want to test if the generated keys are valid. According to Wikipedia the RSA key pair is generated as follows: Choose two.

Elliptic Curve keys

To generate an EC key pair the curve designation must be specified. Note thatJOSE ESxxx signatures require P-256, P-384 and P-521 curves (see theircorresponding OpenSSL identifiers below).

PEM key parsing in Java

Java Bouncy Castle Generate Rsa Key Pair Key

The BouncyCastle library provides a simpleutility to parse PEM-encoded keys in Java, to use them for JWS or JWE later.
