Study of encryption or decryption

Hai aaj ma aap ko btane ja rha hun kese koi message ko encryption or decryption lgaaen .

STEPS

Pehle to ma btana chahta hun ki hota kya ha encryption

Encryption vo cheej ha jo koi bhi file ko hide message ke roop me kisi bhi jgah pe bhej sukte han .
Bina kisi ko show huee or usse decryption bhi kurna aana chahyieee kiu ki jub tuk koi uss message ka key nhi detta tub tuk uss message ko koi nhi pudh nhi sukta .or koi essa kur bhi nhi sukta ke ma uss message ko Minna key ko dalle pudh lun . Essa hir giz mut kurna kiun ki cyber pulice yhi hacking ke roop me aap ko arrest kur sukti ha or 5000 ka jurmana alag se.

STEP 2

Ub ma aap ko btatta hun ki decryption kya hotta ha .

Decryption vo cheej ha jo message ko open hone me mdud kurta ha vo bhi dusre jgh pe .

For example :-  jese koi box me aap ne tala lga diya or usme aap ne bhot jroori saaman rkha ha or vo aap chahte han ki vo disri jgh pe bhi phoch jaae or koi dekh bhi na ske . To aap encryption use kur sukte han ..

Isme aap ko decryption ke bhi mile ga kiu ki agar vi nhi ha to aap vo message kbhi bhi nhi khol sukte .kiu ki agar ke hi nhi hogi to tala khan se khule ga .....

Encryption ke 2 steps han
1.  P2p.   Pear to pear
2  public means ki other

P2p

Isme aap ko koi bhi encryption ho jo khi bhejna ho to vo msg sub ke pass se ho kr nhi gujre ga .
Kiun ki isme aap ko vo hi person choose kurna hoga dekh ske ...jine aap ne ki di huee ha  .jine aap ne authorize kiya hoga ...ye un logo ko nhi dikhe ga jo publick me honge .

Public or Other

Enme aap ka jo message hoga sub ke pass to brod kast ho jaae ga ...but kou usse khol nhi suke ga kiu ki jo person aap ke dvara authorize hoga vo hi open kur sukta ha ....or public ko sirf show ho sukta ha ......

P2p me to aap ko pta hi ha ki kuch person hi han jinhe message show ho rha hoga but  yad rhe public ne dalne se aap ka message sub ko show hoga but khol vhi paae ga jo key dale ok

Suchna ....
