Tests
I. Dummy tap-dummy/
Just an empty main() function
| Compiler | cc65 -Oirs | lcc65 -O3 | vbcc -O3 |
|---|---|---|---|
| Binary size without header | 250 bytes | 452 bytes | 243 bytes |
II. AES256
A byte-oriented AES-256 implementation by Ilya Levin.
This example encrypts and decrypts plain text message. No external library functions are used.
