En la Biblioteca de cryptography Forge Javascript , me está resultando difícil descifrar cómo rebuild las keys públicas y privadas después de que las he usado. It does more work then you specifically require but you can always use forge to generate a key pair and extract one of the primes from that. Can anyone help me with this ? if you're looking to not load in unnecessary modules, I found these are the minimal dependencies that are needed to perform these actions: util, jsbn, oids, asn1, sha256, cipher, cipherModes, aes, prng, random, rsa, pem, x509, pki One more question is, can I also create my own CA with forge? pki. #98. dlongley closed this on Nov 27, 2013.

Android, JavaScript and Python compatible RSA Encryption. var rsa = forge. You just have to set the appropriate flags in the certificate (see the above basicConstraints extension that sets cA to true and the keyUsage extension that sets keyCertSign to true).. With most of this stuff what you'll want to do is output what you want with forge and then compare against what you get .

Here's a. (if you're looking for similar tools in the browser, consider Bluecrypt). Also. generateKeyPair ({bits: 2048, workers: . //generate a key pair of required size var keyPair = forge.pki.rsa.generateKeyPair (4096); //at this point we have 2 primes p and q in the privateKey var p = keyPair.privateKey.p; var q = keyPair . generateKeyPair ({bits: 2048, workers: 2}, function (err .

Install rsa; // generate an RSA key pair synchronously var keypair = rsa. It's somewhat complicated to implement RSA Encryption so that data encrypted on either of these platforms can be easily decrypted on the other platforms and even more so for someone like me who had almost zero knowledge of programming using encryption algorithms.
