Homophonic Cipher
One-to-many substitution cipher that maps each plaintext letter to multiple ciphertext symbols.
How to Use Homophonic Cipher
- Enter plaintext and keep the Default substitution table.
- Choose Encode; each letter randomly selects one of its assigned two-digit codes.
- Expect a different valid sequence on later runs because the choice is random.
- For Decode, paste space-separated two-digit codes and use the same table.
Frequent letters receive more possible codes to flatten symbol frequencies. The audited examples are actual sampled outputs; future runs can legitimately differ.
Examples
Default table, one sampled encode — input:
HELLO
Output:
34 19 52 52 67
The encoder randomly chooses among valid codes, so later output may differ.
Default table, one sampled encode — input:
TEST
Output:
88 24 78 89
The encoder randomly chooses among valid codes, so later output may differ.
