First of all, Hello! I'm new to the site, don't know any english equivalent to "yoroshiku".
So, I was reading the SHA-512crypt generator documentation and found the part:
The default number of rounds for both algorithms is 5,000. To ensure minimal security and stability on the other hand minimum and maximum values for N are enforced:
minimum for N = 1,000
maximum for N = 999,999,999
Bery interesting since in my humble mind if you apply to many rounds in a hashing function you could end up with a collision bringing you back to square one of the hash.
Am I correct? or is my understanding of collisions wrong?
The way I see, you can both cause a collision with too long plain texts or with too many applications of the same hashing function.
Sorry for any grammar errors, I'm not a english-native speaker.
