$key = openssl_random_pseudo_bytes(16); //Create a random key. Keep it safe
$plaintext = "This is my Welcome Text";
$ivlen = openssl_cipher_iv_length($cipher="AES-128-CBC");
$iv = open
我生成一个ssh密钥:
~ ssh-keygen -t rsa -b 4096
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/kurtostfeld/.ssh/id_rsa): rsa_key
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in rsa_key.
Your public key has
