def cipher = javax.crypto.Cipher.getInstance('RSA')
def factory = java.security.KeyFactory.getInstance("RSA")
def PKEY ='' //write your public key here or get it from a variable for your corelation process
def encodedKeySpec = new java.security.spec.X509EncodedKeySpec(PKEY.decodeBase64())
def publicKey = factory.generatePublic(encodedKeySpec)
cipher.init(javax.crypto.Cipher.ENCRYPT_MODE, publicKey)
String textToEncrypt = '' //write your text to encrypt here or get it from a variable for your corelation process
cipherText = cipher.doFinal(textToEncrypt.getBytes()) //cipherText now have your encrypted value
log.info('Encrypted: ' + cipherText.encodeBase64().toString()) // just log the result to view it in log
we will have pubKey as user defined variable for public key
encText as user defined variable for produced cipherText
textToEncrypt as user defined variable for produced cipherText
The code then will be like that :
def cipher = javax.crypto.Cipher.getInstance('RSA')
def factory = java.security.KeyFactory.getInstance("RSA")
def PKEY =vars.get("pubKey") //Getting it from a variable for your corelation process
def encodedKeySpec = new java.security.spec.X509EncodedKeySpec(PKEY.decodeBase64())
def publicKey = factory.generatePublic(encodedKeySpec)
cipher.init(javax.crypto.Cipher.ENCRYPT_MODE, publicKey)
String textToEncrypt = vars.get("textToEncrypt") //getting the text to encrypt from a variable
cipherText = cipher.doFinal(textToEncrypt.getBytes()) //cipherText now have your encrypted value
log.info('Encrypted: ' + cipherText.encodeBase64()) // just log the result to view it in log
vars.put("textToEncrypt",cipherText.encodeBase64().toString())//inserting the ciphertext in user-defined variable textToEncrypt
