If I have a file that I want to monitor for any changes (other than looking at the file date stamps etc).
How do I use the SHA1CryptoServiceProvider() on a file to create a SHA1 Checksum of 开发者_JS百科the file?using (FileStream fs = new FileStream(@\"C:\\file\\location\", FileMode.Open))
There\'s a website that generates a password by joining a master password with the website\'s name (e.g. master password=abc and site=google) then hashing that with SHA1 and then coding the resulting
I thought they were there for security; to check that the file hasn\'t been tampered with. But 开发者_运维百科surely if someone is capable of modifying the file then they are also capable of modifying
A lot of people have recently started using SHA1 over MD5. I 开发者_Python百科know that MD5 has it\'s security flaws but what other reasons is making SHA1 becoming more popular lately?SHA1 is also loo
My iPhone app uses SHA1 for password security over an instant messaging protocol. Will I be required to declare my app as \"containing encryption\" when I submit it to Apple\'s review proc开发者_JS百
Is there any input that SHA-1 will compute to a hex value of fourty-zeros, 开发者_运维知识库i.e. \"0000000000000000000000000000000000000000\"?Yes, it\'s just incredibly unlikely. I.e. one in 2^160, or
Given a set of 100 different strings of equal length, how can you quantify the probability that a SHA1 d开发者_如何学运维igest collision for the strings is unlikely... ?
digest = HMAC.digest(Digest.new(SHA1), Base64.decode64(key), HashString) return Base64.encode64(digest.to_s()).chomp()
After reading this, it sounds like a great idea to store files using the SHA-1 for the directory. I have no idea what this means however, all I know is that SHA-1 and MD5 are hashing algorithms.If I
