A quick hack to re encrypting mule secure properties file

reencrypt.sh

#!/bin/bash

if [ "$#" -ne 4 ]; then
    echo "usage: ./reencrypt.sh <Algo> <Key Source> <source file> <Key Target>";
    exit -1;
fi
ALGO=$1
KEY_SOURCE=$2
FILE=$3
KEY_TARGET=$4

if [ ! -f "$FILE" ]; then
    echo "$FILE does not exists."
    exit -1;
fi

while IFS='=' read -r k v; do
    if [[ $k = *[!\ ]* ]] && [[ $v = *[!\ ]* ]]; then

        if [[ $v =~ \!\[(.*)$ ]]; then
            ENCRYPTED=${BASH_REMATCH[1]}
            ENC=${ENCRYPTED::-2}

            DECRYPTED_STRING=$(docker run --rm nabsha/docker-mule-secure-tool decrypt $ALGO $KEY_SOURCE $ENC)
            ENCRYPTED_STRING=$(docker run --rm nabsha/docker-mule-secure-tool encrypt $ALGO $KEY_TARGET $DECRYPTED_STRING)

            echo "$k=![$ENCRYPTED_STRING]"

        fi

    fi
done < "$FILE"
