Creating a New Key Pair and Self-Signed Certificate Using keytool

keytool -genkey -alias alias -keystore .keystore

Export certificate in binary using keytool, if the certificate is in the key store

keytool -storepass my-keystore-password -alias myalias -export -file outfilename.cer

Export certificate in text format using keytool, if the certificate is in the key store

keytool -storepass my-keystore-password -alias myalias -export -rfc -file outfilename.cer

generates a 1024-bit Digital Signature Algorithm (DSA) key pair.

keytool -genkey -alias alias -keystore .keystore

To create a 1024-bit RSA key:

keytool -genkey -keyalg RSA -keysize 1024 -alias alias -keystore .keystore

using keytool to import a certificate into a keystore

keytool -storepass my-keystore-password -alias myalias -import -file infilename.cer
