Currently I do not have a C# environment to test it. Is it possible you could fix this and provide a pull request?

Hi,

I believe I fixed (in 2.0.6) with this change: base64Encoded = base64Encoded.Replace(" ", "");

Thank you.

Best regards, Ilya Gerasimets

my base64 content:

PHNtaWw+PGhlYWQ+PGxheW91dD48cm9vdC1sYXlvdXQgd2lkdGg9IjMyMHB4IiBoZWlnaHQ9IjQ4MHB4Ii8+PHJlZ2lvbiBpZD0iSW1hZ2UiIGxlZnQ9IjAiIHRvcD0iMCIgd2lkdGg9IjMyMHB4IiBoZWlnaHQ9IjMyMHB4IiBmaXQ9Im1lZXQiLz48L2xheW91dD48L2hlYWQ+PGJvZHk+PHBhciBkdXI9IjUwMDBtcyI+PGltZyBzcmM9Im1tc19pbWctODM4Mjg0NTUwLmpwZyIgcmVnaW9uPSJJbWFnZSIvPjwvcGFyPjwvYm9keT48L3NtaWw+

It call Base64.Decode failed, occur FormatException. But it's success after i change "FromBase64TransformMode.DoNotIgnoreWhiteSpaces" to "FromBase64TransformMode.IgnoreWhiteSpaces" in Base64.cs.

But, the file saved is broken.

I don't know what differences between "FromBase64TransformMode.DoNotIgnoreWhiteSpaces" and "FromBase64TransformMode.IgnoreWhiteSpaces".

Then i chage to return Convert.FromBase64String(base64Encoded), it's work well.

Please refer to it.

Hi.

I had the same problem, in my case I fixed it with a new replace in the code. The actual replace are

base64Encoded = base64Encoded.Replace("\r\n", ""); base64Encoded = base64Encoded.Replace("\t", ""); base64Encoded = base64Encoded.Replace(" ", "");

I added this and it work " base64Encoded = base64Encoded.Replace("!", "");"

the "!" is a valid char in the variant of base64 "Modified Base64 for Regular expressions (non standard)"

https://en.wikipedia.org/wiki/Base64

May be this is not your case but may be another variant of Base64

Sorry for any mistake or the broken english.
