  • Hello, 

    I'm trying to function "createtoken" of this plugin but I've an issue in creating the token.

    I have a private key like this

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

    <<MULTILINE DATA>>

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

    I have added the key in third party credentials but the I receive the error: "Appian JWTTools failed to read private key"

    I tried to remove newlines but the error is the same.

    Any suggestions?


    Thx

    Hi Paolo, 

    The problem seems to be the format of the private key.
    The plugin expects the private key in PKCS#1RSAPrivateKey (PEM header: BEGIN RSA PRIVATE KEY) format and you are setting it in PKCS#8PrivateKeyInfo (PEM header: BEGIN PRIVATE KEY)
    Please double check but I think you might be able to convert from PKCS#8 to PKCS#1: openssl rsa -in private_pkcs8.pem -out private_pkcs1.pem

    Thanks,
    Leandro.
