Bash support for quick AES-256 encryption/decryption with a prompted password. Add to the end of your `~/.bashrc`

.bashrc

# Other .bashrc contents here...

encrypt() {
    # Read password from /dev/tty
    echo -n "Enter password: " > /dev/tty
    read -s PASSWORD < /dev/tty
    echo > /dev/tty
    if [ -t 0 ]; then
        INPUT="$*"
    else
        INPUT=$(cat)
    fi
    echo -n "$INPUT" | openssl enc -aes-256-cbc -pbkdf2 -iter 10000 -md sha512 -pass pass:"$PASSWORD" | base64 --wrap=0
    echo ""
}

decrypt() {
    # Read password from /dev/tty
    echo -n "Enter password: " > /dev/tty
    read -s PASSWORD < /dev/tty
    echo > /dev/tty
    if [ -t 0 ]; then
        # If no input is piped, use the arguments
        INPUT="$*"
    else
        # If input is piped, read from stdin
        INPUT=$(cat)
    fi
    echo -n "$INPUT" | base64 --decode | openssl enc -d -aes-256-cbc -pbkdf2 -iter 10000 -md sha512 -pass pass:"$PASSWORD"
    echo ""
}
