• Show public key fingerprint

  ssh-keygen -l -f /etc/ssh/ssh_host_rsa_key.pub

The name comes from Privacy Enchanced Email. It can contain several certificates and even the private key.

• Get text info about a CSR file

  openssl req -noout -text -in csr-file-name.csr

• 'A CSR is useless once you have the cert'

• Get information about a p12 file

  keytool -list -v -keystore mykeystore.p12 -storetype PKCS12 -storepass 123456

  openssl pkcs12 -in <my pkcs12 file>.p12 -nodes -passin pass:<passphrase, or blank> |openssl x509 -noout -fingerprint

• Get private key from p12

  openssl pkcs12 -in yourP12File.p12 -nocerts -out privateKey.pem

• Get certificate from p12

  openssl pkcs12 -in yourP12File.p12 -clcerts -nokeys -out publicCert.pem

Using keytool to dump information about a p12 with CertAndKey

`keytool -list -v -storetype pkcs12 -keystore <keyStore.p12>`

• Import public/private keys into Mac OS X Keychain (don't just double click them!)

  security import priv_key.p12 -k ~/Library/Keychains/login.keychain

  security import pub_key.pem -k ~/Library/Keychains/login.keychain

• Verify a SHA-1 digest on OS X

  openssl sha1 <file>
