ds54ds5fsewr5f4ds65fd45f6d6f5df5645d6d65

$encoded = md5("Some string") <-- One-way encryption.

 

$encoded = sha1("Some string") <-- One-way encryption but apparently has known flaws.

 

$encoded = base64_encode("Some string");

$decoded = base64_decode($encoded) <-- Encodes rather than encrypts (Two-way)

$encoded = md5("Some string") <-- One-way encryption.

 

$encoded = sha1("Some string") <-- One-way encryption but apparently has known flaws.

 

$encoded = base64_encode("Some string");

$decoded = base64_decode($encoded) <-- Encodes rather than encrypts (Two-way)

 

can you explain it? if you have time...

i am a php newbie so i didnt understand

MD5 and SHA1 basically turn any string into a 32 character hexidecimal (a-f & 0-9) string known as a hash. They're both one-way encryptions meaning that you can only make a string into a hash and can't find the original string from the hash. Well... you can but only by searching databases of hashes which have been recorded. As for base64 I can't really explain that as I don't use it and only know that it's a two-way encryption.

Actually SHA1 is 40 characters

as rallport said, it depends on what your trying to encrypt.

I use MD5 for a lot of encodes and yes I have also heard SHA1 throws up some problems time to time :/
