Unexpected request for Master password for Credential manager (Christian)

Verified it already acted this way in Taverna 2,4 (by Alan)

Run with JCE but without a Credential manager setup

Tried Katy's Workflow: InterproScan without Looping

  • Dialog asking for master password for Credential manager pops up
    • After clicking cancel several times workflow runs as expected
    • So why is this popup happening here?
  • Even pops up when just editing the workflow

Suggestion for Credential Manager

  • Offer a default of master password of "taverna"
  • If user choose "taverna" warn them that they are operating insecurely
  • Then whenever the Credential Manager master password is required check the expected hashcode against the hashcode for "taverna"
    • If it matches assume user does not want to deal with the master password
  • Alternatively add an empty used_default_master_password file as you do with do_not_warn_about_JCE_policy file
  • If they press cancel instead of providing a password same as above.
  • User can change their password to turn of this insecure mode.
  • Testing without JCE shows max password is 7 characters "1234567" worked bit "12345678" failed
    • various 7 digit passwords tested incl symbols and caps and all worked.
    • 7 character limit applies to password for credential manager not passwords saved in the credential manager
      • Tried a 10 character user name and 19 character password with success




  • None
