[waqishah]

Salam!

This is Good.. Main Ap ko Aik Chota Sa Tutorial Main Guide Kar Deta Hun, Baki Yeh Ap ki Technique Hai Ke Ap Ne Is Ko Implement Karna Hai.

Encryption ke leye aik alogrithm hota hai jo ke ap ke Plain Text ko aik aesay format main convert kr deta hai jo ke samaj main nahe ati is ko encryption boltay hain. Similarly Decryption ka bhi aik algorithm hota hai jo ke Encrypted form ko leta hai aur Plain Text(original text) main convert krta hai.

Ab algorithm main kiya cheez hai jo Encrypted Form ko Plain text main aur Plain Text ko Encrypted Form main convert krti hai ? Is ko hum "KEY" boltay hain. Yeh Key Secret honi chahiye.. ap apnay scanerio main Encryption aur Decryption algorithm ko bhi secret rakhain.

Aaein main ap ko aik simple method batata hun jis se ap apnay Text ko Encrypt kr saktay hain

Let us say ke mera password hai 'proxy'. Main simple aik Algorithm banata hun jo meray password ko encrypt kr de main us Algorithm ya function ko name deta huna Encrypt(PlainText,KEY) ab yeh Encrypt ik function hai jo muj se do cheezay poochay ga 'PlainText' jo ke mersa password hai jis ko main ne encrypt krna hai aur "KEY" key main is case main numeric le raha hun.. main yahan key ki value 1 leta hun. ab dekeye

Encrypt(proxy,+1) = qspyz
dekeye is function ne kiya kaam kiya meray plain text ko encrypt kr deya... yahan main ne jo technique use ki hai us main ne simple kiya ke meri "Key" value thi 1 main aur mera text tha proxy.

p + 1 = ( q ) ----> p se next alphabet q hai
r + 1 = ( s ) ----> r se next s & so on,,
o + 1 = ( p )
x + 1 = ( y )
y + 1 = ( z )


decrypt(qspyz,-1)

q - 1 = (p) ----> q se pehlay p & so on
s - 1 = (r)
p - 1 = (o)
y - 1 = (x)
z - 1 = (y)

Dekeye simple +1 se kiya hua ke next alphabet aa geya, ab yeh ap ka encrypted text hai, is ko ap store kr lain database main..Similarly jab ap ne decrypt krna ho to simple ap ne - 1 krna hai. Yeh tehnique samajanay k maksad yehi tha ke ap ko pata chal sakay ke encryption decryption hoti kesay hai. Let me tell you Encryption Decryption ke algorithm banay banae net se mil gatay hain, ap wo bhi implement kr saktay hain


Dekha ap ne ke kis tarhan Encryption aur Decryption hoti hai, yeh technique jo main ne yahan batae bohat old hai aur easily crack ho sakti hai... ap ko apni technique implement krni hai.


Programming main agr ap ne yehi technique implement krni hai to ap ne simple ap ne +1 ya -1 nahe krna.. you need to see which logic you are required!!!!


Main ne apnay is choti se guide maian bohat sari complex cheezaon ko avoid kiya takay basics ki logic samajnay man confusion na ho
Agr samjanay main kuch kami reh gae ho to sorry! Need Furthur help.. you are most welcome.
