I strongly doubt that your code works given it relies on this JSEncrypt library

With regards to your question itself, you can use JDK Securit API in order to encrypt whatever string you want using whatever algorithm you like.

Example Groovy code:

def cipher = javax.crypto.Cipher.getInstance('RSA')
def factory = java.security.KeyFactory.getInstance("RSA")
def publicKeyString='your_public_key_here'
def  encodedKeySpec = new java.security.spec.X509EncodedKeySpec(publicKeyString.decodeBase64())
def publicKey = factory.generatePublic(encodedKeySpec)
cipher.init(javax.crypto.Cipher.ENCRYPT_MODE, publicKey)
cipherText = cipher.doFinal('the string you want to encode'.getBytes())
log.info('Encrypted: ' + cipherText.encodeBase64())

Demo:
