gin-jwks-rsa

This gin-gonic handler aims at providing a JKMS exposing the public key properties needed in the JWT encryption/decryption workflow using RSA.

Usage

Import your own private key

func main() {
    r := gin.Default()

    builder := NewConfigBuilder()
    config, err := builder.
        ImportPrivateKey().
        WithPath("../testdata/private.pem").
        WithKeyId("my-id").
        Build()

    if err != nil {
        fmt.Errorf("error generating conf %v", err)
        return
    }

    r.GET("/.well-known/jwks.json", Jkws(*config))
    r.Run()
}

Generate a private key

func main() {
    r := gin.Default()

    builder := NewConfigBuilder()
    config, err := builder.
        NewPrivateKey().
        WithKeyId("my-id").
        WithKeyLength(2048).
        Build()

    if err != nil {
        fmt.Errorf("error generating conf %v", err)
        return
    }

    r.GET("/.well-known/jwks.json", Jkws(*config))
    r.Run()
}
