SQL Server hashbytes seed
I am able to get identical results between python and T-SQL code with the MD5 algorithm. For example, the NO COLLUSION string hashes to 0x5CA1A58C070F24EF1D4D2900E5727F37 on both platforms.
Example T-SQL code:
SELECT HASHBYTES('MD5', 'NO COLLUSION');

Example Python code:
import hashlib
result = hashlib.md5(b'NO COLLUSION')
print(result.hexdigest())

I'm not an encryption expert, but it's not clear to me what you mean by &quot;SQL's seed&quot;. The MD5 algorithm doesn't appear to call for a random number to be added by the implementer. Such an algorithm would be quite inconvenient because it would result in the same problem that you're running into right now: different implementations of the same hashing algorithm would give different results for the same input.
