Out of date even when it was made, I think it really represents the
cryptography situation as of the 1930's.
Based on a screenplay by Leo Marks - author of Between Silk and Cyanide:
A Codemaker's War 1941-1945.
Essential reading. Leo was the codemaker for SOE. All hand ciphers and
agents.
He wasn't at Bletchley - who called him "the one who got away" - though,
and so no machine ciphers.
The Silk in the title was for OTPs which could be hidden in clothing
from Gestapo/SS searches.
As I said, essential reading.
