Decrypt a JWE into BinData

See more JSON Web Encryption (JWE) Examples

Demonstrates Jwe.DecryptBd, which decrypts a recipient of a loaded JWE and writes the plaintext bytes into a BinData.

    success := false

    jwe := chilkat.NewJwe()

    //  Load the JWE compact serialization to be decrypted.

    success = jwe.LoadJwe(jweCompact)
    if success == false {
        fmt.Println(jwe.LastErrorText())
        jwe.DisposeJwe()
        return
    }

    //  The 256-bit key-wrapping key (base64) for recipient index 0.  In production, obtain the key
    //  from a secure source rather than hard-coding it.

    success = jwe.SetWrappingKey(0,base64Key,"base64")
