Base64 encoding Logic

Nws ua qhov tseem ceeb hauv ob kauj ruam. Thawj kauj ruam yog txhawm rau binary hlua mus rau hauv 6-ntsis blocks. Base 64 tsuas yog siv 6 khoom (xws li 2^6 = 64 cim) kom paub meej encoded cov ntaub ntawv yog printable thiab humanly readable. Tsis muaj cov cim tshwj xeeb muaj nyob hauv ASCII siv.

Ntawm no, kuv yuav encode hauv base64 li cas?

Kuj Paub, qhov point ntawm base64 encoding yog dab tsi? 3 Teb. Base64 yog ib txoj hauv kev los encode binary cov ntaub ntawv rau hauv ASCII cim teeb paub zoo nkauj txhua lub khoos phis tawj, txhawm rau xa cov ntaub ntawv yam tsis tau poob lossis hloov kho cov ntsiab lus nws tus kheej. Piv txwv li, xa ntawv tshuab tsis tuaj yeem cuam tshuam nrog cov ntaub ntawv binary vim lawv xav tias ASCII (cov ntawv nyeem) cov ntaub ntawv.

Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog lub hauv paus 64 encoded hlua?

Hauv computer science, Base 64 yog ib pawg ntawm binary-rau-ntawv encoding schemes uas sawv cev rau cov ntaub ntawv binary hauv ASCII txoj hlua format los ntawm txhais nws mus rau hauv ib tug radix- 64 sawv cev. Lub sij hawm Base 64 keeb kwm los ntawm kev hloov pauv cov ntsiab lus MIME tshwj xeeb encoding . Txhua Base 64 tus lej sawv cev raws nraim 6 cov ntaub ntawv.

Koj encode ntawv li cas?

Koj tuaj yeem hais qhia tus qauv encoding uas koj tuaj yeem siv los tso saib (decode) cov ntawv nyeem

  1. Nyem qhov File tab.
  2. Nyem Options.
  3. Nyem Advanced.
  4. Scroll mus rau ntu General, thiab tom qab ntawd xaiv qhov Confirm file format conversion on open check box.
  5. Kaw thiab rov qhib cov ntaub ntawv.
  6. Nyob rau hauv Hloov Cov Ntaub Ntawv dialog box, xaiv Encoded Text.
