Single string producing two different hash results with SHA-256 Is it possible that a single string produces two different hash results after going through the same SHA-256 hash function? The code I'm working on right now is doing this, and I assumed this should not be possible. Any help?
No.  This doesn't make sense.  SHA-256 is a mathematical function on bit strings.  As such, it doesn't give different answers at different times of day or under different phases of the moon.  It gives different answers only for different inputs.
