From the SecretKeyFactory docs createSeed only supports API 26+ with the current algorithm.

Could we overload this method so it uses a different algorithm based on the API level of the device?

Hi everyone. We use your library in our product which is Wallet based on Stellar network and I faced an issue working with Firebase SDK.

These lines cause problems on Android P in our case:

Security.removeProvider("BC");
Security.insertProviderAt(new BouncyCastleProvider(), 1);

Https requests get stuck when Firebase API updates certificates or something.
I cannot have control over requests inside of Firebase SDK. And this bug happens at some point after use of app & all Firebase requests not working after this point.

This is the exception I get from Firebase when this issue appears:

For example Stellarx uses 15 words.
One possible solution is to make the constructor of Strength public

private Strength(int rawValue) {
        this.rawValue = rawValue;
    }
