The password will have to be encrypted (not hashed), using some other encrytion format and some sort of key will be needed. These sort of method is, normally, not as secure, though.

On forgetting the password i have to email the user his old password. But i am not able to decrypt the password saved in the database. Can anybody help me in creating a decryption code in java for the same. looking fwd for quick replies Thanks Rahul Re: SHA-1 Decyption 15 Years Ago by masijade Well, sorry to tell you this, but SHA-1 is a hash algorithm, it is not [i]meant[/i] to be decoded. SHA-1 in C 15 Years Ago by waqarafridi Can some body tell me how to take SHA-1 of a given string in C. I am using ubuntu 9.04 with kernel 2.6.30. Re: best encryption algorithm? SHA-2,MD5? 12 Years Ago by charles nitro SHA and MD5 are different algorithms. SHA is considered more secure than MD5. And it doesn't matter if you are talking about the implementation of the algorithms that is distributed with PHP or any implementation. They produce the same result md5 in php produces the same result as md5 in any other language. Re: best encryption algorithm? SHA-2,MD5? 12 Years Ago by pritaeas SHA and MD5 are hashes, not encryption algorithms. Re: SHA-256 in .NET 17 Years Ago by IIMarckus My problem is not with the concept -- I've done this sort of thing before in PHP -- but with the syntax. E.g., this is the effect I want: [code]// Pseudocode If (toupper($usernamein) != "JOHNDOE") { print "Username doesn't match" exit } If (computehash($passwordin) != $prehashedpass) { // where $prehashedpass is the … Byte Array SHA-1 Hash 16 Years Ago by ashkash I need to perform a sha-1 hash on a byte array. The byte array needs to be hashed with all combinations of a minimum of 4 bytes to a maximum of all 9 bytes of the following bytes: 00 01 02 03 04 05 06 07 08 So the following are some examples of the byte array that would need to be hashed using a sha-1 hash: 00 01 02 03 00 01 02 04 00 01 02 … Re: Simple sha-1 encryption using openMp 12 Years Ago by n@nnouss@ …#include <iostream> #include "sha1.h" #include <string> using…void DisplayMessageDigest(unsigned *message_digest); int main() { SHA1 sha; unsigned message_digest[5]; sha.Reset(); sha… Why I can't access the web pages by IE (HTTPS with DES-CBC-SHA?) 18 Years Ago by person Hi all, My problem is I can't access web pages by IE6.0.29 when server uses the DES-CBC-SHA or other(DES or DES3) cipher suits.

And why do many people use SHA-2 ,MD5? also what is the most pipular one too? Re: best encryption algorithm?

Re: SHA-1 Algorithm 13 Years Ago by JeffGrigg Generally, hashes are used to verify that the contents of a message has not been changed. There is no known way to "carefully" change the message so that the resulting hash of the message will remain unchanged.
