Cryptographic techniques
Cryptography is a technique used to provide security to information and communications
by using codes. It ensures that only the intended recipient of the information can understand and
process it. In modern times, the cryptographic techniques used are associated with encryption,
converting plain texts to ciphertext for decoding by the intended recipient and decryption,
converting cipher text to plain text. The procedures used to ensure the data in cryptography are
gotten from numerical ideas and calculations make it hard to decode them. The algorithms used
enable cryptographic key generation, data privacy protection verification, digital signing, internet
web browsing, and confidential transactions like debit cards and credit and transactions.
Symmetrical encryption incurs to represent one of the cryptography techniques used to
encrypt and decrypt electronic data using a secret key. In this technique, the encrypted data
cannot engage understood without the secret key to decrypt it. It is typically used for huge
information protection like bulk database encryption. The database is the only information that
can be accessed by the secret key for encryption and decryption. Block and stream algorithm
incurs to represent two types of symmetric encryption. The block entails encoding bits that are
attributed with a secret key in electronic data blocks. The stream cipher algorithm,
pseudorandom cipher digit streams are combined with the information for protection.
Asymmetric encryption incurs to represent another technique of cryptography. The
technique is also known as public-key cryptography. It involves the use of two keys to encrypt
