Usage: jarsigner [OPTION]... FILE ALIAS
jarsigner -verify [OPTION]... FILE
Java ARchive (JAR) file signing and verification tool.
FILE is the .JAR file to sign or to verify.
ALIAS must be a known Alias of a Key Entry in the designated key store. The
private key material associated with this Alias is used for signing FILE. if
ALIAS is required, but was omitted, "mykey" will be used instead.
Signing options:
-keystore URL Location of the key store to use. The default
value is a file-based scheme whose path is the
file named ".keystore" in your home directory.
If URL is malformed, the tool will use URL as a
file-name of a key store; i.e. as if the protocol
was "file:".
-storetype STORE_TYPE Type of the key store to use. If omitted, the
default value is that of the property
"keystore.type" in the security properties file.
-storepass PASSWORD Password to unlock the key store. If omitted, you
will be prompted to provide a password.
-keypass PASSWORD Password to unlock the Key Entry associated with
ALIAS. If omitted, the tool will use the same
password protecting the key store. If this
fails, you will be prompted to provide a password.
