NAME

       gjarsigner - Java ARchive (JAR) file signing and verification tool


SYNOPSIS

       jarsigner [OPTION]... FILE ALIAS

       jarsigner -verify [OPTION]... FILE


DESCRIPTION

       When the first form is used, the tool signs the designated JAR file.
       The second form, on the other hand, is used to verify a previously
       signed JAR file.

       FILE is the .JAR file to process; i.e., to sign if the first syntax
       form is used, or to verify if the second syntax form is used instead.

       ALIAS must be a known Alias of a Key Entry in the designated Key Store.
       The private key material associated with this Alias is then used for
       signing the designated .JAR file.


OPTIONS

       Common options

       The following options may be used when the tool is used for either
       signing, or verifying, a .JAR file.

       -verbose
           Use this option to force the tool to generate more verbose
           messages, during its processing.

       -internalsf
           When present, the tool will include --which otherwise it does not--
           the ".SF" file in the ".DSA" generated file.

       -sectionsonly
           When present, the tool will include in the ".SF" generated file
           --which otherwise it does not-- a header containing a hash of the
           whole manifest file.  When that header is included, the tool can
           quickly check, during verification, if the hash (in the header)
           matches or not the manifest file.

       -provider PROVIDER_CLASS_NAME
           A fully qualified class name of a Security Provider to add to the
           current list of Security Providers already installed in the JVM in-
           use. If a provider class is specified with this option, and was
           successfully added to the runtime --i.e. it was not already
           installed-- then the tool will attempt to remove this Security
           Provider before exiting.

       -help
           Prints a help text similar to this one.

       Signing options

       The following options may be specified when using the tool for signing
       purposes.

       -keystore URL
           Use this option to specify the location of the key store to use.
           The default value is a file URL referencing the file named
           .keystore located in the path returned by the call to
           "java.lang.System#getProperty(String)" using "user.home" as
           argument.

           If a URL was specified, but was found to be malformed --e.g.
           missing protocol element-- the tool will attempt to use the URL
           value as a file-name (with absolute or relative path-name) of a key
           store --as if the protocol was "file:".

       -storetype STORE_TYPE
           Use this option to specify the type of the key store to use. The
           default value, if this option is omitted, is that of the property
           "keystore.type" in the security properties file, which is obtained
           by invoking the static method call "getDefaultType()" in
           "java.security.KeyStore".

       -storepass PASSWORD
           Use this option to specify the password which will be used to
           unlock the key store. If this option is missing, the User will be
           prompted to provide a password.

       -keypass PASSWORD
           Use this option to specify the password which the tool will use to
           unlock the Key Entry associated with the designated Alias.

           If this option is omitted, the tool will first attempt to unlock
           the Key Entry using the same password protecting the key store. If
           this fails, you will then be prompted to provide a password.

       -sigfile NAME
           Use this option to designate a literal that will be used to
           construct file names for both the ".SF" and ".DSA" signature files.
           These files  will be generated, by the tool, and placed in the
           META-INF directory of the signed JAR.  Permissible characters for
           NAME must be in the range "a-zA-Z0-9_-".  All characters will be
           converted to upper-case ones.

           If this option is missing, the first eight characters of the ALIAS
           argument will be used. When this is the case, any character in
           ALIAS that is outside the permissible range of characters will be
           replaced by an underscore.

       -signedjar FILE
           Use this option to specify the file name of the signed JAR. If this
           option is omitted, then the signed JAR will be named the same as
           FILE; i.e., the input JAR file will be replaced with the signed
           copy.

       Verification options

       The following options may be specified when using the tool for
       verification purposes.

       -verify
           Use this option to indicate that the tool is to be used for
           verification purposes.

       -certs
           This option is used in conjunction with the -verbose option. When
           present, along with the -verbose option, the tool will print more
           detailed information about the certificates of the signer(s) being
           processed.
