Fix for Issue #12 - Handle long master passwords

[OffRange]

Summary:

This pull request fixes issue #12, which involves a crash occurring when logging into the app with a long master password. The crash is caused by the bcrypt algorithm's inability to handle passwords longer than 72 characters. To mitigate this issue, the proposed solution is to first hash the password using the SHA-512 algorithm and then compare it with the original hashed password.

Changes Made:

• Modified the password handling mechanism to support long passwords.
• Implemented a LongPasswordStrategy using LongPasswordStrategies.hashSha512(VERSION_2A)
• Updated the relevant function to incorporate the new password handling logic.

Impact:

• The proposed changes enhance the app's robustness and resolve the crashing issue caused by long passwords. By employing the SHA-512 algorithm for hashing long passwords, we can ensure compatibility and prevent crashes during the login process.

Additional Notes:

The changes made in this pull request adhere to the best practices and security guidelines for password handling. The updated password handling mechanism ensures both security and stability while maintaining compatibility with the bcrypt algorithm for shorter passwords.
