About PEM to CRT and KEY Extraction

PEM (Privacy Enhanced Mail) bundle files often contain multiple components including certificates and private keys. This tool extracts both the certificate (.crt) and private key (.key) from a combined PEM bundle file.

PEM bundles typically contain Base64-encoded data wrapped in header/footer lines like -----BEGIN CERTIFICATE----- and -----BEGIN PRIVATE KEY-----. This tool intelligently separates these components so you can use them individually with your web server or application.

Supported Key Types:

• RSA Private Keys (BEGIN RSA PRIVATE KEY)
• PKCS#8 Private Keys (BEGIN PRIVATE KEY)
• EC Private Keys (BEGIN EC PRIVATE KEY)
• Encrypted Private Keys (BEGIN ENCRYPTED PRIVATE KEY)

Common Use Cases:

• Separating certificate and key for Apache/Nginx configuration
• Extracting components from Let's Encrypt fullchain files
• Preparing SSL files for AWS, Azure, or cloud load balancers
• Converting combined PEM exports from certificate authorities
