I am trying to create a certificate with the keytool utility. i need some information on keyUsage, i have seen the javadoc.

however i am not able to understand the the difference between various key usage like :

  1. what is digitalSignature and when it should be used.
  2. what is the difference between keyCertSign and cRLSign and which one to use when?

  • Ad 1. The key will be used to create digital signatures of data.
  • Ad 2. Key will be used to Sign Certificates and Certificate Revocation List

If you just want to create a simple certificate you do not need to define its usage.
