KeyStore password (see --ks). The following formats are supported:
pass:<password> password provided inline
env:<name> password provided in the named
environment variable
file:<file> password provided in the named
file, as a single line
stdin password provided on standard input,
as a single line
A password is required to open a KeyStore.
By default, the tool will prompt for password via console or standard input.
When the same file (including standard input) is used for providing multiple passwords, the passwords are read from the file one line at a time. Passwords are read in the order in which signers are specified and, within each signer, KeyStore password is read before the key password is read.
