Test framework for Z80 ciphers.
Currently there are only aes128, blowfish and speck ciphers and keccak hash available.
This is still a 'proof-of-concept' project, so there are no Z80 decryptors, only encryptors.
The framework contains some test vectors (key, plaintext, ciphertext) and applies them to the corresponding cipher or hash implementations.
The framework uses modified libz80 to count cycles of the simulated Z80
execution. The execution ends as soon as HALT is executed and the consumed
number of cycles returned to the caller.
The pasmo assembler is also modified to support for some synonyms, like exd
for ex de,hl or exa for ex af,af'. More synonyms for index register
halves are added too.
Use make GCRYPT=1 to build with gcrypt support (only for AES and Blowfish).
Build instructions:
- go to directory
cd tst/src
- build pasmo assembler:
cd pasmo;
./configure;
make
- build libz80 library:
cd libz80;
make
-
build libkeccak.so from XKPC project (https://github.com/XKCP/XKCP.git). Use
make asmX86-64/libkeccak.sofor generic amd64 build. You might try generic32/libkeccak.so for other 32bit platforms as a first try. This repo already contains libkeccak.so for amd64, but feel free to re-build it. -
build tests:
make
- run tests:
./main
You can also run specific Z80 tests (that are not run by default):
./main aes
or
./main bf
or
./main speck
or
./main keccak
./main longkeccak will add 1Gbyte hashing test vector to keccak tests. Warning! Using both 'keccak' and 'longkeccak' will pass that 1Gbyte string to Z80 implementation, thus resulting in 5-10 hours of calculations (on a modern peecee hardware).
Test vectors for aes and blowfish are taken from various public sources. First test vector for speck taken from public source, others are generated by me.
