Description Ryan Sleevi 2012-09-21 17:32:08 UTC 
Raised by David Wagner on http://lists.w3.org/Archives/Public/public-webcrypto-comments/2012Sep/0029.html

The definition for AES-CBC mode, http://www.w3.org/TR/WebCryptoAPI/#aes-cbc, does not fully define the type of padding used.

While possible to expose user-selectable options (X.923, ISO/IEC 7616-4, Zero padding), for the use cases identified so far, it may make sense to simply specify this as PKCS7 padding.
