You can feed text into ssh-keygen with a here-document:

Code:
ssh-keygen <<EOF
line1
line2
line3
EOF

You can substitute variables inside it as you like.

Note that the last EOF must be at the beginning of the line, don't even indent it.

kstash

KSTASH(8)						    BSD System Manager's Manual 						 KSTASH(8)

NAME

     kstash -- store the KDC master password in a file

SYNOPSIS

     kstash [-e string | --enctype=string] [-k file | --key-file=file] [--convert-file] [--random-key] [--master-key-fd=fd] [--random-key]
	    [-h | --help] [--version]

DESCRIPTION

     kstash reads the Kerberos master key and stores it in a file that will be used by the KDC.

     Supported options:

     -e string, --enctype=string
	     the encryption type to use, defaults to DES3-CBC-SHA1.

     -k file, --key-file=file
	     the name of the master key file.

     --convert-file
	     don't ask for a new master key, just read an old master key file, and write it back in the new keyfile format.

     --random-key
	     generate a random master key.

     --master-key-fd=fd
	     filedescriptor to read passphrase from, if not specified the passphrase will be read from the terminal.

FILES

     /var/heimdal/m-key is the default keyfile if no other keyfile is specified.  The format of a Heimdal master key is the same as a keytab, so
     ktutil list can be used to list the content of the file.
