The idea itself was manifestly workable but finding a truly one-way function seemed a formidable task. Rivest had an equally enthusiastic supporter in one of his colleagues -- Adi Shamir. Adleman however was less than excited -- he thought the idea was quite impractical and unworthy of pursuing.
Ang ideya mismo ay manifestly magagawa ngunit paghahanap ng tunay na isa-paraan function seemed ng isang mabigat na gawain. Rivest nagkaroon ng isang pantay masigasig bata sa isa sa kanyang mga kasamahan - Adi Shamir. Adleman gayunpaman ay mas mababa kaysa sa nagaganyak - siya-iisip ang mga ideya ay lubos na walang paraan at hindi karapat-dapat ng pursuing.
