EXAMPLE PLEASE!!! about openpgp-php

[singpolyma]

https://github.com/singpolyma/openpgp-php/blob/master/examples/encryptDecrypt.php

Shows encrypt/decrypt using a key. To use a passphrase instead, send the encrypt function an array containing strings. Or you can do both passphrases and keys by mixing them in the array.

Can you please give me a full example for my case?

1. I want to generate a public and private key based on a keypair (EMAIL + PASSPHRASE or just passphrase)
2. Encrypt a message (TEXT, not file. When i ::parsestring public key from keygen i get an error) using public key generated from step 1
3. Decrypt message using private key and PASSPHRASE from step 1

Thank you again for the reply

PS: Also the encryptdecrypt.php uses the same key. Shouldnt Encryption use the public key, and decryption dhe private key?? @singpolyma

This might help you, assuming you already have your way of generating keys:

Test Example

I have set up an example in a unit test file you can place in your project and play around with.

@krisidmisso

@singpolyma You might want to change the example to draw from separate sources for the public and private key to make the example more obvious. I got confused by the "OpenPGP_Crypt_Symmetric" for a sec, too.

Shouldnt Encryption use the public key, and decryption dhe private key??

Every OpenPGP secret key contains a full copy of the public key, so if you happen to have the secret key in memory already you can use to for encryption to save a step, which is what the example is doing. Of course, if you only have the public key then you can use that for encryption just fine as well.

How can I convert binary encryption to ascii?

@singpolyma i had generated public and private key for test from https://pgpkeygen.com/
while decrypting message it always throw

ErrorException {#1227
  #message: "Undefined index: d"
  #code: 0
  #file: "vendor/singpolyma/openpgp-php/lib/openpgp_crypt_rsa.php"

with my private key i did not know why convert_key function celled
