php: how to generate different output for same string
Is there some way to generate different output for same given string, here is example:
That always generates same
fb469d7ef430b0baf0cab6c436e70375 for the given input. How do I generate different encrypted text each time and be able to decrypt it later if needed ?
I have seen functions such as
sha1, etc but they generate same output and secondly I cannot decrypt later if needed.
P.S: I know I can go with one way encryption and compare encrypted texts but for a particular scenario, I have requirement to be able to decrypt text completely if needed later however I am not able to figure out if there is some way or function in php for it.
Any help will be greatly appreciated. Thanks
