Decrypt a string with public key using openssl in VCL app

[saeiddavoody 0]

Hi, In my VCL application I send a request to server and receive a data that encrypted by php openssl_private_encrypt. Now I want to decrypt it with a public key. I have the public key.

1. How should I do that?
2. Is there a third-party component to do that?
3. what difference between using openssl library to decrypt data with public key and decrypting it using other library or pure RSA?

 

Update: Some components such as TMS Cryptography, Delphi-OpenSSL decrypt data with private key not public key using openssl.

 

How should I decrypt the string with public key using openssl?
