Review comment:
1. Why 32 bytes long?
Random Secret Length is 32 characters. I think you thought of it as the size
of the key.
Given, 1 char = 8 bit, 32 chars make up 256 bits.
2. Why AES?
Short answer: AES is trusted within the US NSA for sharing top
secret/security information which means this algorithm is vetted for highest
security clearance!
Long Answer: Breaking a symmetric 256-bit key by brute force requires 2^128
times more computational power than a 128-bit key.
Fifty supercomputers that could check a billion billion (10^18) AES keys per
second (if such a device exists) would, in theory, require about 3×(10^51)
years to exhaust the 256-bit key space. That said, every cryptography algorithm
gets broken eventually, AES seems good for the foreseeable future :)
Aside from this, I will still file a Jira to make the length/algorithm
configurable at cluster level.
