You either must use cipherTextBytes = File.ReadAllBytes(path) or if you are forced to use strings you must first encode the bytes to a valid string using Convert.ToBase64String() share|improve this answer answered Reply bartekm Member 86 Points 98 Posts Re: Length of the data to decrypt is invalid Jun 15, 2011 07:08 AM|bartekm|LINK I had this same issue recently, turned out the web Connect with top rated Experts 15 Experts available now in Live!

Since the stream is in read mode, you can't call FlushFinalBlock yourself or you'll have a problem: you need to ensure that the EOF condition "reads through" the CryptoStream.

With everything required to build a cloud platform and solution, you may feel like the distance between you and the cloud is quite long. A few other issues with your code: A constant doesn't make a good salt The constant salt together with deterministic derivation of the IV from the password means that you're reusing Invalid Length For A Base-64 Char Array Or String.

To that end, I have no idea as to what needs to be done to fix it so that I get 100% encryption/decryption based on a string and supplied key.
Is a "object constructor" a shorter name for a "function with name `object` returning type `object`"? I changed the encryption from DES to Rijndael and the srting that didn't work on the first place worked fine but another string gave me an error.
