That is not all the code. You don't show how you send it to the server, and you didn't show the code on the server. We can't tell what you actually sent, and if you sent the correct string, we can't tell you where the algorithm on the client differs from the one on the server if we only see one. We may also be able to deduce the difference if we knew the exact output of the server's decode. (The "additional characters" you mentioned.)	[reply]

That's not very exact. You seem to have added line breaks. I can probably fix that accurately. But you gave two different strings. I don't trust either. Please be precise; specify what bytes those are.	[reply]

Re^3: Base64 Encoding by jethro (Monsignor) on Feb 20, 2011 at 03:50 UTC
To state the obvious, this can't be all the code, there must be code where the data is sent to the server. Why should that necessarily be error free? What about the remote server, is there some convincing evidence that that code is correct? Since you also encode the key, do you send the key as well? Maybe you appended it wrongly (or just the wrong way) and that gets sent back as additional characters. I notice that the number of additional characters is about what you would expect if you got sent back the base64_decoded cleartext password. But the characters themselves don't look like base64_decoded, so my guess is probably wrong, but might give you a hint in the right direction PS: AFAIK MIME::Base64 is a very old and well-tested module, the chance to find the bug there are pretty slim	[reply]

What a plonker I am, Jethro is correct, I have been including the key in the form transmission when it was nor necessary. Thanks to all that responded to my initial query.	[reply]
