Decrypt a JWE with a Private Key

See more JSON Web Encryption (JWE) Examples

Demonstrates Jwe.SetPrivateKey, which sets the private key used to decrypt a recipient of a loaded JWE.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

    success := false

    jwe := chilkat.NewJwe()

    //  Load the JWE compact serialization to be decrypted.
    jweCompact := "eyJhbGciOiJBMjU2S1ciLCJlbmMiOiJBMjU2R0NNIn0.<...>.<iv>.<ciphertext>.<tag>"
    success = jwe.LoadJwe(jweCompact)
    if success == false {
        fmt.Println(jwe.LastErrorText())
        jwe.DisposeJwe()
        return
    }

    //  The file path is relative to the application's current working directory.  An absolute path
    //  may also be used.  Supply the path appropriate to your own environment.
    //  Load the recipient's private key.
    privKey := chilkat.NewPrivateKey()
    success = privKey.LoadPemFile("qa_data/recipient_privkey.pem")
    if success == false {
        fmt.Println(privKey.LastErrorText())
        jwe.DisposeJwe()
        privKey.DisposePrivateKey()
        return

    //  Set the private key used to decrypt recipient 0.
    success = jwe.SetPrivateKey(0,privKey)
