Class SignedData

java.lang.Object

com.codename1.backend.security.pki.SignedData

public final class SignedData
extends Object

The content and the certificates of a CMS SignedData structure (RFC 5652), the PKCS#7 envelope a .mobileprovision profile, a signed manifest or a detached signature file arrives in.

SignedData signed = SignedData.decode(profileBytes);
byte[] plist = signed.getContent();
List<Certificate> chain = signed.getCertificates();

It reads; it does not judge. Nothing here checks the signer's signature over the content or the chain behind it: validate the certificates with CertificateValidator and trust the content only as far as that goes. Like the rest of this package it reads DER, so a BER encoding with indefinite lengths is reported as such.
