How can I export only the public key to a file(.pem) with PHP?
Of course it is possible to export the whole certificate and a private key but I can't find a solution to export a public key.
The file should look like
-----BEGIN PUBLIC KEY-----

That's the solution. Thanks to https://www.virendrachandak.com/techtalk/encryption-using-php-openssl/
// Generate the public key for the private key
$key = openssl_pkey_get_details($privateKey); // $privateKey is created with openssl_pkey_new()
// Save the public key in public.pem file
file_put_contents('public.pem', $key['key']);

I am trying to pass a string containing content of a RSA private key file to a PHP function ssh2_auth_pubkey_file:
My function looks like this: ssh2_auth_pubkey_file($connection, $ssh_auth_user, $ssh_auth_pub, $ssh_auth_priv, $ssh_auth_pass)
My problem is string $pubkeyfile in my function it is $ssh_auth_priv parameter. Everything works fine when I supply it with a pointer to file for example 'private.pem' but when I pass content of the file as string, I get error.
$ssh_auth_priv = 'private.pem'; works
I have tried:
$ssh_auth_priv = "-----BEGIN RSA PRIVATE KEY-----

I tried file_get_contents to a string, did not work.
My question is how to pass public key as a string, not a pointer to a file.
You will need to write the private key to a temp file and provide the name of that temp file to ssh2_auth_pubkey_file(), eg:
$session = ssh2_connect($host, $port, ['hostkey' => 'ssh-rsa']);
$tempPrivateKeyFileName = tempnam(sys_get_temp_dir(), 'id_rsa');
$fp = fopen($tempPrivateKeyFileName, 'wb+');
fwrite($fp, $yourPrivateKeyContents);
ssh2_auth_pubkey_file($session, $username, $pubkeyfile, $tempPrivateKeyFileName, $passphrase);
unlink($tempPrivateKeyFileName);
It's worth noting writing the private key to a file where it may be read by other processes may be risky depending on your application and environment. At the least you probably want to ensure the private key is encrypted with a passphrase. You may also wish to add a shutdown handler to ensure the temp file is removed if the process exits abnormally. eg:
register_shutdown_function(static function () use ($tempPrivateKeyFileName) {
if (file_exists($tempPrivateKeyFileName)) {
unlink($tempPrivateKeyFileName);
}
});
You can't pass a string for the public key filename argument, it has to be a filename. The function is defined that way.
Create public key OpenSSL in c
RSA *rsaKeyPair;
rsaKeyPair = RSA_new();
BIGNUM* exp = NULL;
exp = BN_new();
BN_set_word(exp, 65537);
RSA_generate_key_ex(rsaKeyPair, 2048, exp, NULL);
/* To get the C-string PEM form: */
PEM_write_bio_RSAPublicKey(bio, rsaKeyPair);
keylen = BIO_pending(bio);
pem_key = calloc(keylen+1, 1); /* Null-terminate */
BIO_read(bio, pem_key, keylen);
printf("%s", pem_key); // public key
Then copy-paste in php code.
$key2 = <<<EOT

I need extract Public Key from it. openssl_pkey_get_details need resource, but how can I create resource from string?
I tried this
$public_key = openssl_pkey_get_details(openssl_pkey_get_public($private));
Error is openssl_pkey_get_details() expects parameter 1 to be resource, boolean given
EDIT 1:
I'm trying solution from #kbarborak bellow, but $pk_get is false:
$pk_string = "-----BEGIN PRIVATE KEY-----\n".chunk_split($data[4], 64, "\n")."-----END PRIVATE KEY-----\n";
$pk_get = openssl_pkey_get_private($pk_string);
die(var_dump($pk_string));

Use BEGIN RSA PRIVATE KEY instead just BEGIN PRIVATE KEY (same for END).
Hope that's help.
openssl_pkey_get_public() returns false if there's an error. So this is was most likely happens and is passing false to openssl_pkey_get_details(). Debug you $private variable.
I'm trying to use the RSA implementation in phpseclib, I thought it would be easier to do the code once in a function and re-use the function.
When I've tried texting the code I get a error saying "decryption error"
Testing also made me realise that the ciphertext was different every time the code ran, so I'm clearly doing something wrong there!
The code for the functions is:
require_once "Crypt/RSA.php";
require_once "Crypt/AES.php";
//Function for encrypting with RSA
function rsa_encrypt($string, $public_key)
{
//Create an instance of the RSA cypher and load the key into it
$cipher = new Crypt_RSA();
$cipher->loadKey($public_key);
//Set the encryption mode
$cipher->setEncryptionMode(CRYPT_RSA_ENCRYPTION_PKCS1);
//Return the encrypted version
return base64_encode($cipher->encrypt($string));
}
//Function for decrypting with RSA
function rsa_decrypt($string, $private_key)
{
//Create an instance of the RSA cypher and load the key into it
$cipher = new Crypt_RSA();
$cipher->loadKey($private_key);
//Set the encryption mode
$cipher->setEncryptionMode(CRYPT_RSA_ENCRYPTION_PKCS1);
//Return the decrypted version
return $cipher->decrypt($string);
}
I've tried to test it using the following:
(The keys are just for testing so that's why its hardcoded).
It is in here that everytime the code is run that the value of $ciphertext changes everytime
//Private key

I think GigaWatt's answer is the correct one. As for this:
Testing also made me realise that the ciphertext was different every
time the code ran, so I'm clearly doing something wrong there!
PKCS#1 padding adds random bytes so the ciphertext's will always be different. The PKCS#1 algorithm however knows when the plaintext ends and the random bytes begin so it's able to separate the two and return you the result you're wanting.
EDIT: I got it to work after I replaced the spaces in your keys with new lines. eg.
$private_key = "-----BEGIN RSA PRIVATE KEY-----

$crypted returns to me encrypted data however decryption echos nothing.
I did an echo of the result and it comes back as NULL any ideas?
Solved. I don't know what happened but after generating new key pairs script worked. I might have possibly mixed up my key pairs
Using openssl rsa to dump the key contents reveals that the private and public keys you posted above have a different modulus. For a matching keypair, the modulus would be identical in the private and public keys. In other words, you definately mixed up different keys there.
To detect this, OpenSSL proper has the RSA_check_key() function to check whether an RSA keypair is usable, but the PHP wrapper for OpenSSL does not seem to expose that function to the user.
Public key:
% openssl rsa -in public_key.pem -pubin -text
Public-Key: (2048 bit)
Modulus:
