# Recently I had to send a password to someone over Skype. Since that's obviously not a good idea, I asked for 
# the person's public SSH RSA key, and used it to encrypt the password itself.


# Convert the public key into PEM format
ssh-keygen -f path/to/id_rsa.pub -e -m pem > ~/id_rsa.pub.pem

# Using the public pem file to encrypt a string
echo "sometext" | openssl rsautl -encrypt -pubin -inkey ~/id_rsa.pub.pem > ~/encrypted.txt

# First of all you need to have a clean clone of the source repository so we didn't screw the things up.

git clone git://server.com/my-repo1.git

# After that you need to do some preparations on the source repository, nuking all the entries except the folder you need to move. Use the following command

git filter-branch --subdirectory-filter your_dir -- -- all

# This will nuke all the other entries and their history, creating a clean git repository that contains only data and history from the directory you need. If you need to move several folders, you have to collect them in a single directory using the git mv command.
