Java - Javascript implementation incompatibility. Possible JS bug parsing the private key #55

Open rupps9800 opened 9 years ago

The following example does not work.... I am generating my keys in Java as per this example http://www.txedo.me/blog/java-generate-rsa-keys-write-pem-file/ or even with my own implementation in Java.

I am working on a project that will depend on the exchange of public keys from client to server and my back end is written in java. It seems like there may be a bug in this js library. If the bug is in the js library I would point it to the shared library you are using as the same example will not work for these guys either https://kjur.github.io/jsrsasign/

Seems like a deeper problem needs to be identified. When I debugged it in chrome I noticed an issue parsing the private key, as this condition is not met by the private key: "if (asn1.sub.length === 9) {"

Please see the RSAKey.prototype.parseKey method.

This may be a non issue, perhaps pkcs8 format is not supported....
