We always save sensitive info on our PC. When an encryptedfs is not usable or we have to put data on a shared filesystem – we can protect ourself a bit better than a locked zipfile with bcrypt.
# bcrypt serverpassword.txt
# bcrypt -o serverpassword.txt.bfe # print file to stdout
# bcrypt serverpassword.txt.bfe # restore serverpassword.txt
Usually I prefer ENCfs
