How to pass jarsigner.exe passphrase via commandline?

Question

I know that this is unsafe, but is there any easy way to pass passphrase to the jarsigner.exe:

jrsigner.exe -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore ...

Enter Passphrase for keystore:

I am running it in batch file.

Answer 1

Well, why do you not simply use the corresponding parameters?

jarsigner -keystore my-keystore -storetype jceks -storepass "test" -keypass "test" my-archive.jar xander 

Broken down into separate lines for better readability (but you have to put all parameters on one line, of course):

jarsigner   -keystore my-keystore    # keystore path name   -storetype jceks         # keystore type (whatever format yours is in)   -storepass "test"        # keystore password   -keypass "test"          # private key password   my-archive.jar           # JAR path name   xander                   # key name (alias) 

Update: Please note with regard to passwords that

• enclosing passwords in double or single quotes is optional if the passwords contain no special characters.
• on the Windows command line you have to use double quotes enclosing passwords with special characters such as space. I am mentioning that because someone previously edited my answer and used single quotes which would simply fail on the Windows command line.
• on UNIX-like systems like Linux or also in the Windows Git Bash or Cygwin you can use both double or single quotes, but with double quotes beware of shell expansion.
