Method Details

createKeyPair

public static KeyPair createKeyPair()

Creates a new standard KeyPair.

This method can be used if no specific key type is required. It returns a "secp384r1" ECDSA key pair.

Returns:

Generated KeyPair

Since:

2.8

createKeyPair

public static KeyPair createKeyPair(int keysize)

Creates a new RSA KeyPair.

Parameters:

keysize - Key size

Returns:

Generated KeyPair

createECKeyPair

public static KeyPair createECKeyPair(String name)

Creates a new elliptic curve KeyPair.

Parameters:

name - ECDSA curve name (e.g. "secp256r1")

Returns:

Generated KeyPair

readKeyPair

public static KeyPair readKeyPair(Reader r)
                           throws IOException

Reads a KeyPair from a PEM file.

Parameters:

r - Reader to read the PEM file from. The Reader is closed after use.

Returns:

KeyPair read

Throws:

IOException

writeKeyPair

public static void writeKeyPair(KeyPair keypair,
 Writer w)
                         throws IOException

Writes a KeyPair PEM file.

Parameters:

keypair - KeyPair to write

w - Writer to write the PEM file to. The Writer is closed after use.

Throws:

IOException

writePublicKey

public static void writePublicKey(PublicKey key,
 Writer w)
                           throws IOException

Writes a PublicKey as PEM file.

Parameters:

key - PublicKey

w - Writer to write the PEM file to. The Writer is closed after use.

Throws:

IOException

Since:
