No offense, but I gather you're not a crypto person.
As soon as you said 'secure' I knew there may be a problem. Merely encrypting data with a good two-way encryption scheme does not make it secure. Procedures, physical security, SOX compliance procedures, audting, etc., all contribute to 'secure'.
I've worked with uninformed management, so I know they think having 'unbreakable' two-way encryption is all that's needed. They don't care if the passwords on all the files are the same, or if someone leaves the password taped to a console.
Unless security is more than encryption and includes a large array of things throughout your company, decent two-way encryption is is not going to mediate any security threats. And is just going to cuase you perosnally problems when people lock up files and can't open them.
FWIW: all two-way encryption schemes can be broken with the exception of the so-called one-time pad (Shannons' Theorem if you want to read about it). It might take several years of brute force attack, but they all can be broken.
Short answer: PGP can be broken, if that's what you mean. There are problems with the random number generators used for a lot of implmentations of it.
The (US) NSA currently deems triple-DES encryption schemes and some other related schemes as something we do not want the bad guys to get. ie., NSA has a difficult time with breaking them. So I would go with triple-DES.

git-tar-tree
GIT-TAR-TREE(1) Git Manual GIT-TAR-TREE(1)
NAME
git-tar-tree - Create a tar archive of the files in the named tree object
SYNOPSIS
git tar-tree [--remote=<repo>] <tree-ish> [ <base> ]
DESCRIPTION
THIS COMMAND IS DEPRECATED. Use git archive with --format=tar option instead (and move the <base> argument to --prefix=base/).
Creates a tar archive containing the tree structure for the named tree. When <base> is specified it is added as a leading path to the files
in the generated tar archive.
git tar-tree behaves differently when given a tree ID versus when given a commit ID or tag ID. In the first case the current time is used
as modification time of each file in the archive. In the latter case the commit time as recorded in the referenced commit object is used
instead. Additionally the commit ID is stored in a global extended pax header. It can be extracted using git get-tar-commit-id.
OPTIONS
<tree-ish>
The tree or commit to produce tar archive for. If it is the object name of a commit object.
<base>
Leading path to the files in the resulting tar archive.
--remote=<repo>
Instead of making a tar archive from local repository, retrieve a tar archive from a remote repository.
CONFIGURATION
tar.umask
This variable can be used to restrict the permission bits of tar archive entries. The default is 0002, which turns off the world write
bit. The special value "user" indicates that the archiving user's umask will be used instead. See umask(2) for details.
EXAMPLES
git tar-tree HEAD junk | (cd /var/tmp/ && tar xf -)
Create a tar archive that contains the contents of the latest commit on the current branch, and extracts it in /var/tmp/junk directory.
git tar-tree v1.4.0 git-1.4.0 | gzip >git-1.4.0.tar.gz
Create a tarball for v1.4.0 release.
git tar-tree v1.4.0^{tree} git-1.4.0 | gzip >git-1.4.0.tar.gz
Create a tarball for v1.4.0 release, but without a global extended pax header.
git tar-tree --remote=example.com:git.git v1.4.0 >git-1.4.0.tar
Get a tarball v1.4.0 from example.com.
git tar-tree HEAD:Documentation/ git-docs > git-1.4.0-docs.tar
Put everything in the current head's Documentation/ directory into git-1.4.0-docs.tar, with the prefix git-docs/.
