# Encryption functions. Requires the GNUpg "gpg" commandline tool. On OS X, "brew install gnupg"
# Explanation of options here:
# --symmetric - Don't public-key encrypt, just symmetrically encrypt in-place with a passphrase.
# -z 9 - Compression level
# --require-secmem - Require use of secured memory for operations. Bails otherwise.
# cipher-algo, s2k-cipher-algo - The algorithm used for the secret key
# digest-algo - The algorithm used to mangle the secret key
# s2k-mode 3 - Enables multiple rounds of mangling to thwart brute-force attacks
# s2k-count 65000000 - Mangles the passphrase this number of times. Takes over a second on modern hardware.
# compress-algo BZIP2- Uses a high quality compression algorithm before encryption. BZIP2 is good but not compatible with PGP proper, FYI.

How to delete a file from a Git repository, but not other users' working copies

Suppose you have, by mistake, added your IDE's project folder (you know, these .idea folders with all kinds of local paths and configuration data and settings in it) to the Git repository of your project. (We're talking about a whole folder here, but the same rules apply to individual files as well.)

Of course, you only realize that two days after the fact and have already pushed it, and your colleagues have already pulled it. They use the same IDE as you do, so whenever they change a setting or fix paths, they can either

• commit that, causing nasty merge conflicts for you and others or
• ignore the changes and carry around a modified file until the end of time without ever committing it.

Why .gitignore won't help

# delete local tag '12345'
git tag -d 12345
# delete remote tag '12345' (eg, GitHub version too)
git push origin :refs/tags/12345
# alternative approach
git push --delete origin tagName
git tag -d tagName
