cryptem

A little tool to simply encrypt files.

I need a simple, short, easy command to encrypt all the content of a folder.
Few options:

• password
• delete clear files when encrypting, encrypted files when decrypting
• scan subfolders
• decrypt

Note: password must be long exactly 16 chars. Note: cryptem ignores files and folders that start with a dot (.).

Prerequisites:

• go
• git

To install, clone the git repo, cd into cmd/cryptem folder and run go install.

# EXAMPLES

# Encrypt all the files inside the folder 
> cryptem -folder . -password "1234567890123456" 

# Encrypt all the files inside the folder 
# delete the originals unencrypted
> cryptem -folder . -password "1234567890123456" -delete

# Encrypt all the files inside the folder
# delete the originals unencrypted
# do the same recursively inside all the subfolders
> cryptem -folder . -password "1234567890123456" -delete -recursive

# Encrypt all the files inside the folder
# overwrite existing .cryptem files
# delete the originals unencrypted
# do the same recursively inside all the subfolders
> cryptem -folder . -password "1234567890123456" -delete -recursive -overwrite

# Adding -decrypt the previous commands perform unencryption
