Privacy Enhanced Mail (PEM) cov ntaub ntawv yog cov thawv ntawv pov thawj uas nquag siv hauv kev teeb tsa daim ntawv pov thawj thaum ntau daim ntawv pov thawj uas ua tiav cov saw hlau raug xa tawm los ua ib cov ntaub ntawv. Lawv yog cov txheej txheem txhais hauv RFCs 1421 txog 1424.
PEM puas yog cov ntaub ntawv tseem ceeb?
Privacy Enhanced Mail (PEM) cov ntaub ntawv yog hom Public Key Infrastructure (PKI) file siv rau cov yuam sij thiab daim ntawv pov thawj.
PEM puas yog pej xeem lossis tus yuam sij ntiag tug?

PEM format yog dab tsi?
PEM lossis Privacy Enhanced Mail yog a Base64 encoded DER daim ntawv pov thawj. PEM daim ntawv pov thawj feem ntau siv rau lub vev xaib servers vim lawv tuaj yeem txhais tau yooj yim rau hauv cov ntaub ntawv nyeem tau siv cov ntawv nyeem yooj yim. Feem ntau thaum qhib cov ntaub ntawv PEM encoded hauv cov ntawv nyeem, nws muaj cov headers thiab footers txawv heev.
PEM file vs CRT yog dab tsi?
pem ntxiv cov ntaub ntawv nrog chained nruab nrab thiab cov ntawv pov thawj hauv paus (xws li. ca-bundle cov ntaub ntawv rub tawm los ntawm SSL.com), thiab -inkey PRIVATEKEY. key ntxiv tus yuam sij ntiag tug rau CERTIFICATE. crt (daim ntawv pov thawj qhov kawg).
