OpenSSL
Encrypt and decrypt a file[1] (GPG can also be used for encrypting and decrypting files)
Using aes-256-cbc cypher, You will be prompted for a password when encrypting that has to be used for decrypting.[2]
- Encrypt file (
openssl enc):
openssl enc -aes-256-cbc -in un_encrypted.data -out encrypted.data- You can use
filecommand to verify file type.
file encrypted.data encrypted.data: openssl enc'd data with salted password
- Encrypt file providing password on the command line, be aware that your password will be store on history of your shell):
openssl aes-256-cbc -a -salt -in twitterpost.txt -out foo.enc -pass file:<( echo -n "someGoodPassword" )
- Decrypt file (
openssl enc -d):
openssl enc -d -aes-256-cbc -in encrypted.data -out un_encrypted.data
