Add crypt.[ch] and update md5sum and sha1sum Factor out the code from md5sum and sha1sum into a util function. Use FILE * instead of a file descriptor. This will make it a bit easier/more consistent when we implement support for the -c option. 2013-07-07 14:29:45 +00:00			`struct crypt_ops {`

Refactor cryptcheck() to allow multiple list-files and stdin Previously, it was not possible to use sha1sum test.c \| sha1sum -c because the program would not differenciate between an empty argument and a non-specified argument. Moreover, why not allow this? sha1sum -c hashlist1 hashlist2 Digging deeper I found that using function pointers and a modification in the crypt-backend might simplify the program a lot by passing the argument-list to both cryptmain and cryptcheck. Allowing more than one list-file to be specified is also consistent with what the other implementations support, so we not only have simpler code, we also do not silently break if there's a script around passing multiple files to check. 2015-03-01 21:51:52 +00:00			`int cryptcheck(int, char *, struct crypt_ops , uint8_t *, size_t);`
Forgot to remove argc from function decl Thanks FRIGN for noticing this. 2013-11-30 21:11:19 +00:00			`int cryptmain(int, char *, struct crypt_ops , uint8_t *, size_t);`
Don't use buffered IO (fread) when not appropriate fread reads the entire requested size (BUFSIZ), which causes tools to block if only small amounts of data are available at a time. At best, this causes unnecessary copies and inefficiency, at worst, tools like tee and cat are almost unusable in some cases since they only display large chunks of data at a time. 2017-01-02 01:00:33 +00:00			`int cryptsum(struct crypt_ops , int, const char , uint8_t *);`
We do not name parameters in declarations 2013-11-22 13:40:08 +00:00			`void mdprint(const uint8_t , const char , size_t);`
