I've implement a modular 'Base64Codec' class that could be useful.

certainly, the question is: where/how can we try it? :)

Added Area-Library, Triaged labels.

Hi,

This is required for one of our external customers, as well as is required to interface with AWS services. Was hoping to bump up to unblock dependencies. Thanks!

Removed Priority-Medium label.
Added Priority-High label.

Let me put in support for base64 encoding in the dart:crypto library. It is useful there and then it will be available. If we decide that it belongs somewhere else later that is fine and the crypto library can then get it from there.

Set owner to @madsager.
Added Started label.

#import('dart:crypto');

main() {
  print(CryptoUtils.bytesToBase64('Hello world'.charCodes()));
}

Added Fixed label.

Looking at r8108, it only seems to cover encoding. I don't think this issue should be marked as "fixed", since there is no decoding -- or is it?

Re-opened to handle the decode case.

Added Triaged label.

Thanks Ladislav. You are right, this should not be closed since I only added encoding support. I think encoding is the only thing that really makes sense for the crypto library, so we need to consider if there is a better place for a general base64 encoder and decoder.

Until this landed, dart:crypto only contained one-way functions (hashes). Base64 is the first reversible function added to dart:crypto, and I think that if encoding is suitable for this library, then decoding is too. After all, when real encryption algorithms come, they will need to come with decryption :-)

I think we should have a base64 encoding/decoding library in packages.

Added this to the M2 milestone.

I agree we should have encode and decode functionality in a library. In the meantime though, there is a basic decoder available in pkg/webdriver/base64decoder.dart.

And it is available in dart:crypto as well: http://api.dartlang.org/docs/continuous/dart_crypto/CryptoUtils.html

Almost :) We still need base64 to bytes. Unless I missed it?

Heh, yes, we are missing that. I think I have mentioned dart:crypto before and forgotten about the missing other direction. :-)

Removed this from the M2 milestone.
Added this to the M3 milestone.
