Braclayrab Posted January 17, 2007 Share Posted January 17, 2007 Hi,I'm trying to implement the RSA library available from Pear(http://pear.php.net/package/Crypt_RSA/). I'm having trouble getting it working. I'm passing the public key to my client which then encrypt a password with javascript. I retrieve it from CryptRSA(the php library) with the following code:bin2hex($_SESSION['key_pair']->getPublicKey()->getExponent())Similarly for the modulus. However, the javascript library is not functional with the keys that are being generated by CryptRSA If I pass the public key to the javascript library as well I can't even use it to decrypt on the client(javascript) side.CryptRSA also appears to sometimes generate even numbers for p and q! Am I misunderstanding something? do p and q not actually need to be prime?Has anyone else ever gotten CryptRSA working in this way? Is there perhaps a better way for me to be doing the encryption on the client side? Does anyone know of another PHP RSA library that I can try?TIA!-Clay Link to comment https://forums.phpfreaks.com/topic/34529-rsa-help/ Share on other sites More sharing options...
Braclayrab Posted January 17, 2007 Author Share Posted January 17, 2007 Update:I may have figured out the issue, looks like and endianness problem. The math libraries are possibly spitting out the numbers in the wrong order. Here's a bunch of p's, The second digit is always odd and the same is true for the moduli:0bcdd4dce4ecf3fb9daeb6bec6ced6dea3a8b0b8c0c8d0d8a9b8c0c8d0d8e0e7adccd4dce4ecf4fca5adb6bec6ced6dd8fa0a8b0b8c0c7cff9c1cad2d9e2e9f1c1c5cdd5dee7eff7a1a1acb4bcc4ccd4b5cad2dae2eaf2f925c9d0d8e0e8f0f89bacb5bdc5cdd4dcc5abb3bbc3cbd3dbcdc9d2dae2e9f1f9c5cdd5dde5edf4fc19b6bdc6ced6dee6bfc9d1d9e1e9f1f925c9d0d8e0e8f0f813bfc6ced6dee5ede9a6afb7bfc7cfdcbfc9d1d9e1e9f1f9adc3cbd3dbe2eaf2d5b2bac2cad2dce41dc2cad2dae2e9f19fb0b8c0c8d0d8e0bda7afb7bec6ced6c5c2cad2dae2e9f18ba3acb4bcc5cdd5b9d0d8e0e8f0f7ffc1cdd5dde5edf5fd49525b636a727ae69399a1a9b0b8c0c8e9b0b8c0c8d0d7dfe9c5ced5dde5edf5adb2bbc3cad2dae2b3b3bac2cbd3dbe2d5cbd3dbe3ebf3fa Link to comment https://forums.phpfreaks.com/topic/34529-rsa-help/#findComment-162677 Share on other sites More sharing options...
