Process for generating ES512 keys? about clj-jwt

[venantius]

Perhaps somewhat explicitly, trying to use a key generated either by:

openssl ecparam -name secp521r1 -genkey -noout

or:

ssh-keygen -t ecdsa -b 521

Gets me the following exception:

user=> (clj-jwt.key/private-key "common/resources/security/ec512-key")

java.security.NoSuchAlgorithmException: ECDSA KeyFactory not available
 org.bouncycastle.openssl.PEMException: unable to convert key pair: ECDSA KeyFactory not available

So, the problem here turns out not to have been an issue with my generation of ECDSA keys, but rather the fact that the BouncyCastle Provider hadn't been configured (refer to JIRA issue on BouncyCastle here: http://www.bouncycastle.org/jira/browse/BJA-625)

To get this working, you just need to add the BouncyCastle Provider to the java.security.Security class as follows:

(. java.security.Security addProvider (org.bouncycastle.jce.provider.BouncyCastleProvider.))

Ah, I just saw e13b665. So really all you need to do is to update the README to make clear that the process for ingesting a ECDSA key is different than how it used to be.
