Hi, in base64 encoded string, I would like to know if there are any future conflict or any complication if I remove encoded strings that ends with equal characters "=" ?

I'm using MIME::Base64, encode_base64($str,"");

For some strings after encoded will have trailing equal character(s). Some with 1 characters some with 2 characters. I have tested myself by removing all equal characters and decode it back without any problem.

I just would like to seek for experienced guru here is it ok if I completely remove all equal characters in base64 encoded string?

Also I'm not quite understand of 65-character subset ([A-Za-z0-9+/=]). Does this means the encoded strings will contain such characters?

I understand A-Za-z0-9, but +/= means what characters?

Thanks.
