node-forge offers only a generic encrypt function with RSAES encryption system:
var publicKey = pki.publicKeyFromPem(pem);
// encrypt data with a public key using RSAES PKCS#1 v1.5
var encrypted = publicKey.encrypt(bytes, 'RSAES-PKCS1-V1_5');
I would like to use 3DES instead of RSAES.
Is there any misconception in the world of cryptography in my question?
