Hi Francois,

I have the exact same problem on multiple hosts. Some hosting providers
have a broken PHP install.

I created a bug about it here (it's realy not a bug in caretaker):

http://forge.typo3.org/issues/show/5516

I use the following solution on a server that does have a proper PHP.
Whenever I need a key-pair, I call the following script frome somewhere
on the 'sane PHP' server:

________________________________________________________________________________

<?php

    $keyPair = openssl_pkey_new();

    openssl_pkey_export($keyPair, $privateKey);

    $publicKey = openssl_pkey_get_details($keyPair);
    $publicKey = $publicKey['key'];

    $publicKey = str_replace("\n", '|', $publicKey);
    $privateKey = str_replace("\n", '|', $privateKey);

?>

<html>
	<head>
	<script type="text/javascript">
		function SelectAll(id)
		{
			document.getElementById(id).focus();
			document.getElementById(id).select();
		}
	</script>

	</head>
	<body>
		<form name="blip">
			Public: <input id="pub" onclick="SelectAll('pub');" name="pub"
value="<?php echo $publicKey ?>" size="150" /><br/>
			Private: <input id="priv" onclick="SelectAll('priv');" name="priv"
value="<?php echo $privateKey ?>" size="150" /><br/>
		</form>
	</body>
</html>
