Hi, Is there an option to use RSA Asymmetric encryption with a 2048 key using

OAEP padding, as we want to generate an encrypted value of 256 chars, and using PB2017 R3 it is only generating 128 chars?

 

e.g

lblb_data = Blob(a_sPassword, EncodingANSI!)

// Generate the private key
lnv_CrypterObject.AsymmetricGenerateKey(RSA!, 2048, i_lblb_privKey, i_lblb_pubKey)

// Encrypt data using RSA
lblb_encrypt = lnv_CrypterObject.AsymmetricEncrypt(RSA!, lblb_data, i_lblb_pubKey)

 

Length of lblb_encrypt is 128, and our security requirements are for 256 chars
