The OpenSSL Software Foundation (OSF) is a legal entity created to hustle money in support of OpenSSL. The media have noted that in the five years since it was created OSF has never taken in over $1 million in gross revenues annually. OSF typically receives about US$2000 a year in outright donations and sells commercial software support contracts. For the team members not having any other employment or day job such contract work is their only non-trivial source of income.”]
