Basics of Cryptography

In this post, we will primarily look into basics of cryptography. First, will look into basic terminologies used in the world of cryptography.

Plaintext

3e5d6f2c4b2cbe9c475f9a3865f6c266 This is the original message or original data that needs to be encrypted. In simple terms, An original message that needs to be encrypted is known as plaintext.

Ciphertext

source link This is the encrypted message or output message which is produced as output. It mainly depends on plaintext and secret key. For a given plaintext, different secret keys will provide two different ciphertexts. The ciphertext is unintelligible and human can’t understand the ciphertext.

Secret Key

go There are two different inputs to encryption algorithm one is plaintext and another one is the secret key. The secret key is a value which is independent of plaintext and the algorithm used.

Encryption Algorithm:

Decryption Algorithm:

go to link It is again an algorithm which is reverse of the encryption algorithm. It takes secret key and Ciphertext as input and will provide Plain text as output. Secret key should be same as what we have used for encryption.

Encryption:

Decryption:

Cryptanalysis:

Cryptanalysis is a technique which used to decipher a ciphertext without the knowledge of encryption details. It is also known as “Breaking the code”.

Cryptography:

Cryptology:
