Hi,

How to get encrypted string only in symbols, means it should not contain any letter or digit, and also the length of the encrypted string should be 25. Please provide decryption method also for the same.

Please reply.

Thanks..

What I have tried:

I tried encryption and decryption using TripleDESCryptoServiceProvider class which gives encrypted string, but I am not able to get encrypted string in only symbolic form and also can not limit the length. Is there any property or method to do this?

But why would need such a weird logic?
Can you brief us the requirement to do as such?

Actually it is my project's requirement that encrypted password should be in symbols only and length should not be greater than 25.
Please help..

Then you are expected to do the work.

It's an unreasonable requirement so push back on it, there is no valid reason why encrypted passwords should conform to this, your hands are tied by the encryption method you use. As suggested in Solution 1, if you use hashing instead then it's far easier to get a result that is 25 chars or less as hashing tends to result in shorter results.

Solution 1

No. You cannot force a maximum length on encrypted data, as it is massively dependent on the length of the input data.
You should not be encrypting passwords anyway, you should be hashing them - see here: Password Storage: How to do it.[^]
Hashing does "fix" the length of the output data.
