Encrypting Cocoa Resources with Custom Build Shell Script

I am encrypting some resources in my Cocoa app using the following script (Source):

DIRNAME=EncryptedResources
ENC_KEY="abcdefghijklmnopqrstuvwxyz123456"

INDIR=$PROJECT_DIR/$DIRNAME
OUTDIR=$TARGET_BUILD_DIR/$CONTENTS_FOLDER_PATH/$DIRNAME

if [ ! -d "$OUTDIR" ]; then
  mkdir -p "$OUTDIR"
fi

for file in "$INDIR"/*
do
  echo "Encrypting $file"
  "$PROJECT_DIR/crypt" -e -k $ENC_KEY -i "$file" -o "$OUTDIR/`basename "$file"`"
done

However the script doesn't handle sub-directories within the EncryptedResources directory. I have several nested sub-directories so what would be the easiest way to modify the shell script to handle the sub-directories and have those output correctly.

FYI I used the following:

DIRNAME=ENCRYPTEDCONTENT
ENC_KEY="INSERT ENCRYPTION KEY HERE"

INDIR=$PROJECT_DIR/$DIRNAME
OUTDIR=$TARGET_BUILD_DIR/$CONTENTS_FOLDER_PATH/Resources/$DIRNAME

if [ ! -d "$OUTDIR" ]; then
mkdir -p "$OUTDIR"
fi


while IFS= read -r -d $'\0' dir;
do
DIRECTORY=`echo $dir | sed -e "s,$INDIR,$OUTDIR,g"`
mkdir -p "$DIRECTORY"
done < <(find "$INDIR" -type d -print0)

while IFS= read -r -d $'\0' file;
do
OUTFILE=`echo $file | sed -e "s,$INDIR,$OUTDIR,g"`
if [ ! -d "$file" ]; then
echo "Encrypting $file"
"$PROJECT_DIR/crypt" -e -k $ENC_KEY -i "$file" -o "$OUTFILE"
fi
done < <(find "$INDIR" -type f -print0)

You need to use the find command instead of your for loop.

find $INDIR -exec "$PROJECT_DIR/crypt" 
    -e -k $ENC_KEY -i {} -o "$OUTDIR/`basename {}`" \; # all on one line

might be a good approximation of what you need to do, but find is very hard to use, and I'm working from memory.
