Since I am new to encryption and have recently been losing stuff, I decided to start a file that contains some passwords for online accounts and whatnot, encrypt it, back it up (and keep a single copy on Google Drive....cloud storage seems insecure to me.)
I was wondering about using GPG though.
Is the default algorithm, CAST5, sufficient?
gpg -c file uses it
Is there any chance that my file could be broken by Google? It uses a long password that seems secure.
Should I add extra information throughout to act as "additional entropy"? Maybe
dd if=/dev/random >> file
And the most important question...is GPG even right for this job-encrypting basic text files. Is there a better, mroe secure option, or a faster option?
