Hi,

I'm trying get OAuth's work, but I'm having difficulty with my RSA key fromat.

I have generated a 2048 RSA key with openssl genrsa -out MyModules.com.pem 2048

I converted my key to a PKCS8 Key openssl pkcs8 -topk8 -nocrypt -in MyModules.com.pem -outform PEM > MyModules.com_pk8.key

the generated key is a base64 key file

-----BEGIN PRIVATE KEY-----

MIIEvwIBADANBgkqhkiG9w0BAQEFAAUTrwSSkEGCgSBKgq10FElAAgEAoIBAQDAx

[...] r9w+yPgzMm2ypZD1bqXj34faqw==

-----END PRIVATE KEY-----

Once I linked my new key within gadgets.properties

When I called OAuth's signer method, I got this Exception:

java.security.spec.InvalidKeySpecException: java.security.InvalidKeyException: invalid key format
