About
SPECK block cipher
The functions with 'x' at the end is setkey/encrypt combined in one call.
- speck64.c
64-bit block size, 128-bit keys
void speck64_setkey(const void *in, void *out);
void speck64_encrypt(int enc, void *in, const void *keys);
void speck64_encryptx(void *in, const void *keys);
- speck128.c
128-bit block size, 256-bit keys
void speck128_setkey(const void *in, void *out);
void speck128_encrypt(int enc, void *in, const void *keys);
void speck128_encryptx(void *in, const void *keys);
- spk64.asm
x86 assembly code based on speck64.c using 32-bit stdcall convention.
See bld32.bat for example of how to compile.
- spk128.asm
x86-64 assembly based on speck128.c using Microsoft fastcall convention.
See bld64.bat for example of how to compile.
