AES and ChaCha20 zoo tshaj plaws symmetrical ciphers siv , raws li thaum pib ntawm lub xyoo pua 21st. Qhov txawv ntawm lawv yog, yooj yim muab, ua ib qho thaiv thiab kwj cipher , yog li ntawd txawv nyob rau hauv ceev.

Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog daim ntawv zoo tshaj plaws ntawm encryption?

RSA lossis Rivest-Shamir-Adleman encryption algorithm yog ib hom kev encryption muaj zog tshaj plaws hauv ntiaj teb. Nws txhawb nqa qhov ntev ntawm qhov tseem ceeb, thiab nws yog qhov raug pom 2048- thiab 4096- ntsis yuam sij. RSA yog asymmetric encryption algorithm.

Ib sab saum toj no, txoj kev encryption twg yog siv dav tshaj plaws thiab vim li cas? Cov feem ntau siv symmetrical algorithm yog Advanced Encryption Standard (AES), uas yog Ameslikas hu ua Rijndael. Qhov no yog tus qauv tsim los ntawm US National Institute of Standards and Technology hauv 2001 rau cov encryption Cov ntaub ntawv hluav taws xob tau tshaj tawm hauv Asmeskas FIPS PUB 197.

Tib neeg kuj nug, dab tsi yog qhov cipher ruaj ntseg tshaj plaws?

Advanced Encryption Standard, AES, yog symmetrical encryption algorithm thiab ib qho ntawm cov ruaj ntseg tshaj plaws.

Qhov twg zoo dua AES lossis RSA?

AES yog ib tug symmetric encryption algorithm - ib tug yuam sij yuav siv tau los encrypt, thiab ces decrypt cov lus. RSA yog ib qho asymmetric encryption algorithm - ib khub ntawm cov yuam sij yog siv, ib qho koj khaws rau koj tus kheej (private), thiab ib qho koj koom nrog rau lwm lub ntiaj teb (public).
