Generate hashes for macports from URL

macport_hash.sh

#!/usr/bin/env bash

# Check if a URL is provided
if [ "$#" -ne 1 ]; then
    echo "Usage: $0 <url>"
    exit 1
fi

# Get the URL from the command-line argument
url="$1"

# Create a temporary file
temp_file=$(mktemp)

# Fetch the file
curl -sL "$url" -o "$temp_file"

# Get the file size
file_size=$(wc -c < "$temp_file")

# Calculate hashes
rmd160=$(openssl rmd160 "$temp_file" | awk '{print $2}')
sha256=$(openssl sha256 "$temp_file" | awk '{print $2}')

# Output results
echo "RMD160: $rmd160"
echo "SHA256: $sha256"
echo "  Size: $file_size"

# Clean up the temporary file
rm "$temp_file"
