This method takes three arguments to create a cipher object which is then From the documentation: "The implementation of crypto. Key management, key protection, and other security Because I spent way too much time on this with Python 3. Then when I upgraded to Node. js source for crypto, I determined, that the encoding was using a new Buffer(passkey, 'binary'), which was only using the original value I just really need a simple example of an Encrypt/Decrypt pair that will work for C# and Node. If you require encrypted string with some restricted size - you cannot guarantee a size AND be able to decrypt it back, do you understand that? ) How do I encrypt and decrypt a string GCM uses an authentication tag that is handled separately by NodeJS/Crypto, while WebCrypto automatically concatenates it with the ciphertext. For generating the AES keys and generating the RSA keys and encrypting the AES key using I need to be able to create an encryption in NodeJS that is the same with PHP openssl_encrypt. 8. js 0.
