Overview

Package clib holds all of the dirty C interaction for go-xmlsec.

Although this package is visible to the outside world, the API in this package is in NO WAY guaranteed to be stable. This package was initially meant to be placed in an internal package so that the API was not available to the outside world.

The only reason this is visible is so that the REALLY advanced users can abuse the quasi-direct-C-API to overcome shortcomings of the "public" API, if any (and of course, you WILL send me a pull request later... won't you?)

Please DO NOT rely on this API and expect that it will keep backcompat. When the need arises, it WILL be changed, and if you are not ready for it, your code WILL break in horrible horrible ways. You have been warned.

Functions

func FindSignatureNode

func FindSignatureNode(n PtrSource) (types.Node, error)

func XMLSecCryptoAppKeyCertLoad

func XMLSecCryptoAppKeyCertLoad(key PtrSource, certFile string, format KeyDataFormat) error

func XMLSecCryptoAppKeyLoad

func XMLSecCryptoAppKeyLoad(file string, format KeyDataFormat) (uintptr, error)

XMLSecCryptoAppKeyLoad calls xmlSecCryptoAppKeyLoad to load a key from file

func XMLSecCryptoAppKeyLoadMemory

func XMLSecCryptoAppKeyLoadMemory(buf []byte, format KeyDataFormat) (uintptr, error)

XMLSecCryptoAppKeyLoadMemory calls xmlSecCryptoAppKeyLoadMemory to load a key from an in memory buffer. This function acceses the byte buffer directly, so make sure not to touch the buffer from some other goroutine

func XMLSecDSigCtxCreate

func XMLSecDSigCtxCreate(mngr PtrSource) (uintptr, error)

XMLSecDSigCtxCreate calls xmlSecDSigCtxCreate with a nil parameter and returns a pointer to the new struct

func XMLSecDSigCtxDestroy

func XMLSecDSigCtxDestroy(ctx PtrSource) error

XMLSecDSigCtxDestroy calls xmlSecDSigCtxDestroy on the underlying C pointer, if available.

func XMLSecDSigCtxSetKey

func XMLSecDSigCtxSetKey(ctx PtrSource, key PtrSource) error

XMLSecDSigCtxtSetKey sets the C pointer for key to the signKey slot of the C pointer for ctx.
