- Public-key cryptography could theoretically have been used in 1939, but practical challenges made it unlikely.
- Enigma used symmetric encryption, which was convenient but had vulnerabilities like codebook capture.
- Asymmetric encryption, invented decades later, allows separate keys for encryption and decryption, enhancing security.
- Manual calculation of keypairs and encryption/decryption was possible but tedious and error-prone.
- Key management and usability were significant hurdles for deploying public-key cryptography in the 1930s.
- Mechanical computers of the era could have assisted, but portability and complexity remained issues.
- The mathematics behind public-key cryptography were simple enough for 1930s mathematicians to understand.
- Despite theoretical feasibility, the practical implementation of public-key cryptography in 1939 would have been highly challenging.
