∟"keytool" and "keystore" from JDK

∟Generating CSR (Certificate Signing Request)

This section provides a tutorial example on how to use the 'keytool -certreq' command to generate a CSR (Certificate Signing Request) for the public key stored in a key entry.

In the third example, I want to generate a CSR (Certificate Signing Request) for the public key stored in key entry. The CSR can be then sent to a CA (Certificate Authority) and singed by the CA: 

herong> keytool -certreq -alias my_home  -keypass My1stKey \
   -keystore herong.jks -storepass HerongJKS -file my_home.csr

type my_home.csr
