you can't decode sha1 hash.

a cryptographically strong hash function exhibits 2 features: it irreversible , minimizes collisions. irreversibility means original data cannot reconstructed hash. cf. encryption, must reversible (see write-only memory.) collision occurs when 2 different sets of data generate same hash.

c++ - Troubles when compiling phash program -

here (probably) simple problem: i'm trying use perceptual hashing library phash ubuntu 11.10. had ffmpeg installed, way i've done: sudo apt-get install libphash0 sudo apt-get install libphash0-dev then tried compile program: #include <iostream> #include <phash.h> using namespace std; int main() { ulong64 myhash=0; ph_dct_imagehash("test.jpg", myhash); cout<<myhash<<endl; } when compiling, prints out: undefined reference `ph_dct_imagehash' any suggestion? should do? in advance! matteo monti you forgot link phash library, linker cannot find function. try adding -l phash gcc command line (or update makefile). if doesn't work, maybe you'll need specify library path (the location of *.a file) using -l "/usr/lib/"
