You can generate the encrypted passwords pretty easily with perl:

perl -e 'print crypt("password","salt")."\n";'

replace 'password' with the word you want to encrypt, and 'salt' with a
random salt string.

For DES style passwords, salt should be any two characters:
perl -e 'print crypt("mySecretPassword","XR")."\n";'

For MD5 passwords, you use the format '$1$salt' where the '$1$' is
literal, and the salt is up to 8 characters:
perl -e 'print crypt("mySecretPassword","$1$ABCDEFGH")."\n";'
