Make the `filename' parameter to HASHFile() and HASHFileChunk() const ok pedro@, millert@
20 years ago
Different sha1 functions (taken from netinet's if_sha1.c) that are more consistent with md4/md5 functions.

Added sha1 (secure hash function).

Add function prototypes.

Use a common source file for all the hash helper functions that previously lived in foohl.c. The foohl.c files are now generated via sed, though perhaps cpp could be used in the future. Use u_int8_t instead of unsigned char for the buffers struct fooContext. Add constants for buffer lengths and use them in function prototypes and the man pages. This is basically cosmetic surgery; there should be no functional changes. OK deraadt@

Make the bit count u_int64_t instead of two u_int32_t. Adapted from changes Niklas made to the md5 code long ago. OK hshoexer@

o Ansi function headers o Add __BEGIN_DECLS/__END_DECLS to include files o Safe macros o Remove useless variable assignment in the End function of *hl.c o Some minor KNF, needs more From Dan Weeks

20 years ago
Add Pad and FileChunk functions for each family of hash functions. The Pad function does padding like in Final but does not finish processing. The FileChunk function creates a digest from a portion of a file. Also made the length parameters consistent (and size_t).
20 years ago
Make the 2nd arg to SHA1Transform const again and unifdef SHA1HANDSOFF. It was defined before and there is no need to for this knob...
20 years ago
Undo some recent prototype changes; it is legal to pass the helper functions can take a NULL buf pointer. They will malloc memory as needed in this case.
