Method Detail

generate

public static RSAKeys generate()

Generates a random RSA keypair.

Returns:

the instance.

fromKeyFiles

public static RSAKeys fromKeyFiles(String publicKeyResource,
                                   String privateKeyResource)
                            throws IOException,
                                   NoSuchAlgorithmException,
                                   InvalidKeySpecException

Creates an instance with the given key pair. For more information see loadPublicKey(String) and loadPrivateKey(String).

Parameters:

publicKeyResource - the resource path to the key file, e.g. "/publicKey.txt"

privateKeyResource - the resource path to the key file, e.g. "/privateKey.txt"

Returns:

the instance.

Throws:

IOException - in case the files could not be read.

NoSuchAlgorithmException - see KeyFactory.getInstance(java.lang.String).

InvalidKeySpecException - see KeyFactory.generatePublic(java.security.spec.KeySpec).

loadPublicKey

public static PublicKey loadPublicKey(String publicKeyResource)
                               throws IOException,
                                      NoSuchAlgorithmException,
                                      InvalidKeySpecException

Loads the public key from the given file. The key is expected to be encoded according to the X.509 standard and in base64 format (pem).

Parameters:

publicKeyResource - the resource path to the key file.

Returns:

the PublicKey instance.

Throws:

IOException - in case the file could not be read.

NoSuchAlgorithmException - see KeyFactory.getInstance(java.lang.String).

InvalidKeySpecException - see KeyFactory.generatePublic(java.security.spec.KeySpec).

loadPrivateKey

public static PrivateKey loadPrivateKey(String privateKeyResource)
                                 throws IOException,
                                        NoSuchAlgorithmException,
                                        InvalidKeySpecException

Loads the private key from the given file. The key is expected to be according to PKCS #8 standard and in base64 format (pem).

Parameters:

privateKeyResource - the resource path to the key file.

Returns:

the PrivateKey instance.

Throws:

IOException - in case the file could not be read.

NoSuchAlgorithmException - see KeyFactory.getInstance(java.lang.String).

InvalidKeySpecException - see KeyFactory.generatePublic(java.security.spec.KeySpec).

getPublic

public PublicKey getPublic()

Returns:

the public key of the pair.

getPrivate

public PrivateKey getPrivate()

Returns:

the private key of the pair.
