## Request signatures
|
|
|
|
|
|
|
|
|
|
If `signature_key` is defined, proxied requests will be signed with the
|
|
|
|
|
`GAP-Signature` header, which is a [Hash-based Message Authentication Code
|
|
|
|
|
(HMAC)](https://en.wikipedia.org/wiki/Hash-based_message_authentication_code)
|
|
|
|
|
of selected request information and the request body [see `SIGNATURE_HEADERS`
|
2019-08-11 17:07:03 +02:00
|
|
|
in `oauthproxy.go`]({{ site.gitweb }}/oauthproxy.go).
|

|
|
|
|
|
|
|
|
`signature_key` must be of the form `algorithm:secretkey`, (ie: `signature_key = "sha1:secret0"`)
|
|
|
|
|

|
