BGZF block-level encryption for VCF, BCF, BAM

This page describes a proof of concept implementation of BGZF block-level encryption which works for VCF, BCF, BAM and in general anything compressed with bgzip. The key requirement is that 1) the files remain .tbi and .csi indexable and 2) no changes to existing tools relying on HTSlib are required.

For more please check this PDF presentation.

Download and compiling

To download, compile and test the functionality, run the following sequence of commands:

# get the software
git clone --branch=crypto git://github.com/pd3/htslib.git
cd htslib
# the autotools are used only to make openssl optional
autoheader
autoconf
./configure --enable-openssl
# compile
make
# test
./test/test.pl

In order to test with bcftools and samtools, the openssl-aware version of htslib must be linked with pkg-config openssl --libs. For BCFtools, there is a modified version of Makefile which you can test here

git clone --branch=crypto git://github.com/pd3/bcftools.git
cd bcftools
make
