    We are developing an app for cryptography in both IOS and Android. The app needs to read any one of (i) the pre-master secret, (ii) the master secret, and/or (iii) the PSK negotiated by the standard libraries and TLS 1.3. Assume IOS 14+ or Android 11+. Our research doesn't show how to read any of (i) - (iii) above for network connections we create, either on IOS and Android and the OS stock TLS libraries. The only option seems to be building OpenSSL into our apps, which we want to avoid. So, the project is to confirm, for both IOS and Android, either : - (A) code to read any of (i) - (iii) above for our own App, or - (B) the values (i) - (iii) cannot be read and then OpenSSL (or equivalent) must be used instead.
