Hi i would like to know best encryption technique for text file encryption and ecr开发者_StackOverflowyption.
Conclusion: SHA-1 is safe against preimage attacks, however it is easy to compute, which means it is easier to mount a bruteforce or dictionary attack. (The same is true for successors like SHA-256.)
I read a while back that Quantum Computers can break most types of hashing and encryption in use today in a very short amount of time(I believe it was mere minutes). How is it possible? I\'ve tried re
After reading the topic \"Is MD5 really that bad\", I was thinking about a better solution for generating开发者_Go百科 hashes. Are there better solutions like Adler, CRC32 or SHA1? Or are they broken
I\'m by no means a cryptography expert, I have been reading a few questions around Stack Overflow and on Wikipedia but nothing is really \'clear cut\' in terms of defining an IV and its usa开发者_开发
What\'s the best way to prevent a dictionary attack? I\'ve thought up several implementations but they all seem to have some flaw in them:
You are on a submarine and there is an encrypted message开发者_JS百科 that you want to read. Two people must use their keys at the same time in order to obtain the plain text.What is best cryptographi
I have a quick little app that steps through the possible symmetric encryption methods.I get them with the following line:
Is calculating an MD5 hash less CPU intensive than SHA-1 or SHA-2 on \"standard\" laptop x86 hardware? I\'m interested in general information, not specific to a certain chip.
In Crypto开发者_如何学编程 communities it is common to measure algorithm performance in cycles/byte. My question is, which parameters in the CPU architecture are affecting this number? Except the cloc
