So far I was giving him a public key. One day when he received a content encrypted by my private key, if he was able to decrypt it - that meant that it's really from me. If public key was compromised, that would change nothing because the only thing ...
openssl_public_decrypt()解密data之前通过openssl_private_encrypt()进行加密并将结果存储到decrypted。 您可以使用此功能,例如检查消息是否由私钥所有者编写。 参数 datadecryptedkey key必须是用于加密数据的相应公钥。 padding padding可以是OPENSSL_PKCS1_PADDING,OPENSSL_NO_PADDING其中之一。
