encryption returning false

[Superior126]

I'm trying to encrypt some text with a server public key, but it keeps returning false for whatever reason.

Example pub key from server:

-----BEGIN PUBLIC KEY-----
MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA3fQZaIIUSnWYVR++XoHZ
g7GQS996veS+vxY+FF7Oy9Kd943XHrzrYMuCOaOruB6SEZzu2U1xrXnEbTTdwNcj

lnF+wWnrhBE/0EcGyepXpQ+EwoNGe3vG04LS2pUPOZswetQrgTYAUFrvgicnvhiw
MQIDAQAB
-----END PUBLIC KEY-----

Client code:

// Create a new JSEncrypt instance
const encryptor = new JSEncrypt();

// Set the server's public key
encryptor.setPublicKey(server_pub_key);

// Encrypt the JSON string using the encryptor
const encryptedCredentials = encryptor.encrypt(jsonCredentials);

console.log(encryptedCredentials)

i also have the similar issue after i upgraded to latest version. now i get error message jsencrypt_1.JSEncrypt is not a constructor and encrypt() method returns string | boolean(false), any ideas?

Most probably the public key is invalid, for some reason. Double check that.

The way to declare your public key is :

const publicKeyCasting =
  "-----BEGIN PUBLIC KEY-----MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDY0xIs5oSVl8dxCW4zDTtIdtfOVMjT8bI6l6tDb3BW6HSIAXqEsp6wfeVHJ+7LHFDGSn4TrURpL6FFKHPz7EVzZrcZjNU+jn8l2W9hDXnFc/v3qR3SRXuG71ZUiCP3g8j1SdY+sB0Yn0046PdFiWrIX8qiqMpNX2fHiJH5uq71/QIDAQAB-----END PUBLIC KEY-----"

Same problem here. Tried every variation of encoding, preceding key with the "-----BEGIN PUBLIC KEY-----" and following with "-----END PUBLIC KEY-----"... it all results in false.
