Which platforms? From one Linux "platform" to another:

Encrypt:

Code:

$ openssl enc -aes-256-cbc -e -in /file/to/encrypt -out /file/to/save

(You will be prompted for a password)

Decrypt:

Code:

$ openssl enc -aes-256-cbc -d -in ~/file/to/decrypt -out ~/file/to/save

there is probably a better way than this but if all else fails set up a truecrypt container of about the right size and copy your files into it. It then works like a cross-platform tarball as there are truecrypt versions for w$ & mac

Just made a scritp, cuz I will never remind the function, seems ok:

Code:

#!/bin/sh


if [ "$1" == "--help"   ] ; then
    echo "-er to encrypt and remove, -d to decrypt, arg1 is source , arg2 is target"
	exit
	exit 0
fi


if   [  "$1" == "-e"  ]  && [ "$2" !=  "" ] && [ "$3" !=  "" ]  ; then 
	echo "Encrypting $2 to $3"	
	openssl enc -aes-256-cbc -e -in $2 -out $3
fi



if   [  "$1" == "-er"  ]  && [ "$2" !=  "" ] && [ "$3" !=  "" ]  ; then 
	echo "Encrypting $2 to $3"	
	openssl enc -aes-256-cbc -e -in "$2" -out "$3"
	rm "$2"
fi


if   [  "$1" == "-d"  ]  && [ "$2" !=  "" ] && [ "$3" !=  "" ]  ; then 
	echo "Decrypting $2 to $3"	
	openssl enc -aes-256-cbc -d -in "$2" -out "$3"
fi


if [ "$2" ==  "" ] || [ "$3" ==  "" ]  ; then
	echo "Missing one parameter for encryption"
fi
