let rsa =  forge.pki.rsa;
let keypair = rsa.generateKeyPair({bits: 2048, e: 0x10001});

let encrypted = keypair.publicKey.encrypt(forge.util.createBuffer('你我他','utf8'), 'RSAES-PKCS1-V1_5');
console.log(typeof encrypted); console.log('--------------');
let decrypted = keypair.privateKey.decrypt(encrypted, 'RSAES-PKCS1-V1_5');

output:
