standards:
- [XML Signature Syntax and Processing](https://www.w3.org/TR/xmldsig-core)
- [XML Encryption Syntax and Processing](https://www.w3.org/TR/xmlenc-core/)
## Documentation
Complete XMLSec library documentation is published on [XMLSec website](https://www.aleksey.com/xmlsec/).
## License
XMLSec library is released under the MIT Licence (see the [Copyright file](Copyright).
## Building and installing XMLSec
### Prerequisites
XMLSec requires the following libraries:
- [LibXML2](http://xmlsoft.org)
- [LibXSLT](http://xmlsoft.org/XSLT/)
And at least one of the following cryptographic libraries:
- [OpenSSL](http://www.openssl.org)
- [NSS](https://firefox-source-docs.mozilla.org/security/nss/index.html)
- [GCrypt/GnuTLS](https://www.gnutls.org/)
- MS Crypto API (Windows only)
- MS Crypto API NG (Windows only)
For example, the following packages need to be installed on Ubuntu to build
XMLSec library:
```
# common build tools
apt install automake autoconf libtool libtool-bin gcc
# ltdl is required to support dynamic crypto libs loading
apt install libltdl7 libltdl-dev
# core libxml2 and libxslt libraries
apt install libxml2 libxml2-dev libxslt1.1 libxslt1-dev
# openssl libraries
apt install libssl1.1 libssl-dev
# nspr/nss libraries
apt install libnspr4 libnspr4-dev libnss3 libnss3-dev libnss3-tools
# gcrypt/gnutls libraries
apt install libgcrypt20 libgcrypt20-dev libgnutls28-dev
# required for building man pages and docs
apt install help2man man2html gtk-doc-tools
```
### Building XMLSec on Linux, Unix, MacOSX, MinGW, Cygwin, etc
To build and install XMLSec library on Unix-like systems run the following commands:
```
gunzip -c xmlsec1-xxx.tar.gz | tar xvf -
cd xmlsec1-xxxx
./configure [possible options]
make
make check
make install
```
To see the configuration options, run:
```
./configure --help
```
### Building XMLSec on Windows
See [win32/README.md](win32/README.md) for details.
