Method Details

RegisterKeypair

public static KeyGenerator.SSHKeyPair RegisterKeypair()
                                               throws IOException,
InterruptedException

Generates an Ed25519 SSH key pair.

Returns:

an KeyGenerator.SSHKeyPair containing the private and public keys

Throws:

IOException - if key generation fails

InterruptedException - if the process is interrupted

generateKeyPair

public static KeyGenerator.SSHKeyPair generateKeyPair(String keyType,
 int keySize)

InterruptedException

Generates an SSH key pair using the system's ssh-keygen command.

Parameters:

keyType - the type of key

keySize - the size of the key in bits

Returns:

generated KeyGenerator.SSHKeyPair

Throws:

IOException - if an I/O error occurs

InterruptedException - if the process is interrupted

generateRSAKeyPair
