## Proposed API Changes in Future Versions of Node ## crypto.DEFAULT_ENCODING
The default encoding to use for functions that can take either strings
or buffers. The default value is `'buffer'`, which makes it default
to using Buffer objects. This is here to make the crypto module more
easily compatible with legacy programs that expected `'binary'` to be
the default encoding.
Note that new programs will probably expect buffers, so only use this
as a temporary measure.
## Recent API Changes
The Crypto module was added to Node before there was the concept of a The Crypto module was added to Node before there was the concept of a
unified Stream API, and before there were Buffer objects for handling unified Stream API, and before there were Buffer objects for handling
binary data. binary data.
As such, the streaming classes don't have the typical methods found on As such, the streaming classes don't have the typical methods found on
other Node classes, and many methods accept and return Binary-encoded other Node classes, and many methods accepted and returned
strings by default rather than Buffers. Binary-encoded strings by default rather than Buffers. This was
changed to use Buffers by default instead.
A future version of node will make Buffers the default data type. This is a breaking change for some use cases, but not all.
This will be a breaking change for some use cases, but not all.
For example, if you currently use the default arguments to the Sign For example, if you currently use the default arguments to the Sign
