It is designed to make access 1.24 +to public key crypto engines like GnuPG or GpgSM easier for 1.25 +applications. GPGME provides a high-level crypto API for encryption, 1.26 +decryption, signing, signature verification and key management. 1.27 + 1.28 +GPGME uses GnuPG and GpgSM as its backends to support OpenPGP and the 1.29 +Cryptographic Message Syntax (CMS). 1.30 + 1.31 +GPGME runs best on GNU/Linux or *BSD systems. Other Unices may 1.32 +require small portability fixes, please send us your patches. 1.33 + 1.34 +See the files COPYING, COPYING.LESSER, and each file for copyright and 1.35 +warranty information. The file AUTHORS has a list of authors and 1.36 +useful web and mail addresses. 1.37 + 1.38 + 1.39 +Installation 1.40 +-------------- 1.41 + 1.42 +See the file INSTALL for generic installation instructions. 1.43 + 1.44 +Check that you have unmodified sources. See below on how to do this. 1.45 +Don't skip it - this is an important step! 1.46 + 1.47 +To build GPGME, you need to install libgpg-error (>= 1.11) and 1.48 +Libassuan (>= 2.0.2). 1.49 + 1.50 +For support of the OpenPGP protocol (default), you should use the 1.51 +latest version of GnuPG (>= 1.4) , available at: 1.52 +ftp://ftp.gnupg.org/gcrypt/gnupg/. For support of the CMS 1.53 +(Cryptographic Message Syntax) protocol and lot of other features, you 1.54 +need a GnuPG version >= 2.0. 1.55 + 1.56 +For building the GIT version of GPGME please see the file README.GIT 1.57 +for more information. 1.58 + 1.59 + 1.60 +How to Verify the Source 1.61 +-------------------------- 1.62 + 1.63 +In order to check that the version of GPGME which you are going to 1.64 +install is an original and unmodified one, you can do it in one of the 1.65 +following ways: 1.66 + 1.67 +a) If you have a trusted Version of GnuPG installed, you can simply check 1.68 + the supplied signature: 1.69 + 1.70 + $ gpg --verify gpgme-x.y.z.tar.gz.sig 1.71 + 1.72 + This checks that the detached signature gpgme-x.y.z.tar.gz.sig is 1.73 + indeed a a signature of gpgme-x.y.z.tar.gz. The key used to create 1.74 + this signature is either of: 1.75 + 1.76 + "pub 2048R/4F25E3B6 2011-01-12 Werner Koch (dist sig)" 1.77 + "pub 1024D/87978569 1999-05-13 1.78 + Marcus Brinkmann <Marcus.Brinkmann@ruhr-uni-bochum.de> 1.79 + Marcus Brinkmann <mb@g10code.com>" 1.80 + 1.81 + If you do not have this key, you can get it from any keyserver. You 1.82 + have to make sure that this is really the key and not a faked one. 1.83 + You can do this by comparing the output of: 1.84 + 1.85 + $ gpg --fingerprint 0x4F25E3B6 1.86 + 1.87 + with the fingerprint published elsewhere. 1.88 + 1.89 +b) If you don't have any of the above programs, you have to verify 1.90 + the SHA1 checksum: 1.91 + 1.92 + $ sha1sum gpgme-x.y.z.tar.gz 1.93 + 1.94 + This should yield an output _similar_ to this: 1.95 + 1.96 + fd9351b26b3189c1d577f0970f9dcadc3412def1 gpgme-x.y.z.tar.gz 1.97 + 1.98 + Now check that this checksum is _exactly_ the same as the one 1.99 + published via the announcement list and probably via Usenet. 1.100 + 1.101 + 1.102 +Documentation 1.103 +--------------- 1.104 + 1.105 +For information how to use the library you can read the info manual, 1.106 +which is also a reference book, in the doc/ directory. The programs 1.107 +in the tests/gpg/ directory may also prove useful. 1.108 + 1.109 +Please subscribe to the gnupg-devel@gnupg.org mailing list if you want 1.110 +to do serious work. 1.111 + 1.112 +For hacking on GPGME, please have a look at doc/HACKING.
