Encrypt single field with private key in KeyStore and encode base64

[Former Member]

Hello Experts,

I have a requirement to encrypt single field in the payload with Certificate and private key stored in NWA keystore with SHA256withRSA and encode it base64. I had referred below links

https://blogs.sap.com/2015/09/07/signing-the-request-message-using-certificates-and-encoding-the-mes...

Signature signature = Signature.getInstance("SHA256withRSA"); signature.initSign((PrivateKey) String.getKey(alias, password.toCharArray())); signature.update(plaintext.getBytes("UTF-8"));

byte[] rsa_text= signature.sign();

I'm unable to get it for single field. Can you please provide code snippet for single key.

Regards,

Rajesh

You need public key for encryption. wikipedia

check this below using some randon key

check this reply on how to access the keystore.

if you can create key successfully, then you should be able to perform encryption. search you will find code.
