Cryptography → Securing Information :-
Cryptography information और communication को सुरक्षित रखने की technique है, जिसमें data को ऐसे रूप में बदला जाता है जिससे unauthorized person उसे आसानी से समझ या access न कर सके।
Cryptography का मुख्य उद्देश्य data की Confidentiality, Integrity, Authentication और Security को बनाए रखना है।
Main Components of Cryptography
Plaintext – Original readable data.
Encryption – Plaintext को unreadable form में बदलना।
Ciphertext – Encryption के बाद प्राप्त unreadable data।
Decryption – Ciphertext को वापस readable form में बदलना।
Key – Encryption और Decryption में उपयोग होने वाली value।
Example Plaintext ↓ Encryption + Key ↓ Ciphertext ↓ Decryption + Key ↓ Plaintext Example
यदि message है:
HELLO
Encryption के बाद यह किसी unreadable form में बदल सकता है:
X7#P9
और सही key के द्वारा Decryption करने पर वापस:
HELLO In English - Cryptography → Securing Information
Cryptography is a technique used to secure information and communication by converting data into a form that unauthorized persons cannot easily understand or access.
The main purpose of Cryptography is to maintain the Confidentiality, Integrity, Authentication, and Security of data.
Main Components of Cryptography
Plaintext – Original readable data.
Encryption – Converting plaintext into an unreadable form.
Ciphertext – The unreadable data obtained after encryption.
Decryption – Converting ciphertext back into readable form.
Key – A value used during Encryption and Decryption.
Example Plaintext ↓ Encryption + Key ↓ Ciphertext ↓ Decryption + Key ↓ Plaintext Example
If the message is:
HELLO
After encryption, it may be converted into an unreadable form:
X7#P9
And after Decryption using the correct key, it becomes:
HELLO
