* Add a SHA1 implementationLukas Fleischer2011-10-051-0/+241
Add an implementation of the SHA1 hash algorithm based on a public domain project by Steve Reid <sreid@sea-to-sky.net>. You can get the original sources from: ftp://ftp.funet.fi/pub/crypt/hash/sha/sha1.c We will need this for several things. File names of note files will be generated based on a hash their content instead of using a random name. Items can be uniquely identified using a hash. In addition to the regular sha1_init(), sha1_update() and sha1_final() operations, our implementation also contains wrappers for hashing a string or a stream.
