To convert a .crt file to a .p12 (PKCS#12) file, you’ll need:

• Your certificate file (your_cert.crt)
• The private key file (your_key.key)
• (Optional) The CA bundle file (ca_bundle.crt)

You can use the openssl command like this:

bashCopyEditopenssl pkcs12 -export \
  -in your_cert.crt \
  -inkey your_key.key \
  -out your_cert.p12 \
  -name "your_alias" \
  -certfile ca_bundle.crt

Explanation:

• -in your_cert.crt: Your certificate
• -inkey your_key.key: Your private key
• -out your_cert.p12: Output .p12 file
• -name "your_alias": Alias for the key in the keystore
• -certfile ca_bundle.crt: (Optional) Chain/intermediate certificates
