I'm looking at using Theodore T'so's pwgen (on linux/ubuntu) with its sha1 (-H) feature to generate passwords that I should be able to recreate later using the same file and seed.
I briefly looked to see what alternatives there might be if this particular app (pwgen in unix) is not available to me at any point. Is this a valid consideration? Is there an alternative application that will let me recreate the same password (given the same file and seed of course)?
Whilst this might to some extent be a unix/ubuntu app availability question, I want to hear from security folk on the pros and cons of this approach, hence this question on this forum.
