[go-nuts] Does crypto/AES work on hardware that doesn't have the aes instruction set? Hello, Will crypto/aes, cipher/GCM work on hardware without embedded aes support?

[Sean]

Hello,

Will **crypto/aes**, **cipher/GCM** work on hardware without embedded aes 
support?

What I want to know is how these packages respond in cases where there is 
no embedded AES support (fast is not important).

[go-nuts] DumpRequestOut and RoundTripper

[Jason Meckley]

We have a lot of service to service calls in our application, and 
throughout our code we have blocks of code to add http headers for tracing 
and authentication, we are now adding debug logs to dump the request and 
the response.

The documentation states "do not modify the request" 
, which is a vague statements 
about what can/should be done in a round tripper.

Would it be in violation of documentation and specs to use 
httputil.DumpRequestOut and httputil.DumpResponse in a round tripper?

I found this post 
, but 
it still doesn't seem definitive on the subject.

thank you in advance, Jason

Re: [go-nuts] nil

[Marcin Romaszewicz]

I updated your example with a couple of nil checks which work in this
situation, so have a look after reading that nil error link above.

How can the output of the program be explained? Why checking for nil gives 
false??
