com.codename1.security.PublicKey

public final class PublicKey
extends Key

A public key -- paired with a PrivateKey to form a key pair. Carries the algorithm name ("RSA" or "EC") and the encoded key bytes.

For interop with PEM files (-----BEGIN PUBLIC KEY-----) feed the X.509-SubjectPublicKeyInfo (SPKI) DER bytes to fromX509(String, byte[]); for raw RSA modulus/exponent use rsa(byte[]).

Method Details

fromX509

public static PublicKey fromX509(String algorithm,
 byte[] x509Der)

Wraps an X.509 / SubjectPublicKeyInfo (SPKI) DER blob. This is the format produced by openssl rsa -pubout or openssl ec -pubout.

rsa

public static PublicKey rsa(byte[] x509Der)

Convenience: build an RSA PublicKey from a fromX509(String, byte[]) X.509 blob.
