What is Cryptography?<\/strong><\/h2>\n\n\n\nCryptography is a vital tool for safeguarding data sent over the internet. <\/p>\n\n\n\n
It is the creative transformation of data into an unreadable format, only the intended recipient will be able to understand and use it.<\/p>\n\n\n\n
As a result, cryptography is primarily concerned with securing and protecting data from cyber thieves or anybody other than the intended recipient. <\/p>\n\n\n\n
Therefore, Cryptography allows people to communicate safely over the Internet.<\/p>\n\n\n\n
However, to learn about the Role of Cryptography <\/a>in Information Security, you can refer to the Blog.<\/p>\n\n\n\nThe different cryptographic methods are – <\/strong><\/h2>\n\n\n\nWhat is hashing?<\/h2>\n\n\n\n
It\u2019s a cryptographic method that converts text into a fixed-length, irreversible string called a hash value or digest.<\/p>\n\n\n\n
A single bit of change in the original text can bring an avalanche effect to the hashed string and will result in a different hash. <\/p>\n\n\n\n
A good hash function should be complex and should not reproduce the same hash value for two different inputs.<\/p>\n\n\n
\n![\"hashing\"](\"https:\/\/cloudkul.com\/blog\/wp-content\/uploads\/2021\/07\/hash.png\")
<\/a><\/figure><\/div>\n\n\nWe use hashing to ensure the integrity of the message. <\/p>\n\n\n\n
For example: <\/strong>many stores provide software along with their hash value so that users can ensure the integrity by calculating the hash value of downloaded\/purchased software on their own.<\/p>\n\n\n\nHash functions<\/a> are also used to avoid duplicity of data, to avoid storing clear text passwords database administrators use functions to store passwords in hashed value.<\/p>\n\n\n\nSome widely used Hash cryptographic<\/strong><\/strong> algorithms are – <\/strong> MD5(Message digest) and SHA-2( Secure Hash Algorithm).<\/p>\n\n\n\nWhat is Encoding?<\/h2>\n\n\n\n
Mapping a character with another to make it understandable by that application or machine. <\/p>\n\n\n\n
Here encoding is used to ensure that the application can understand the delivered string and be able to process it, rather than keeping the information secure.<\/p>\n\n\n\n
Encoded strings<\/a> can be decoded using the same scheme that is used to encode, a key is not required for both the processes.<\/p>\n\n\n\n![\"encoding\"](\"https:\/\/cloudkul.com\/blog\/wp-content\/uploads\/2021\/07\/encode.png\")
<\/a><\/figure><\/div>\n\n\nThe above snippet shows an example where a text(“♠”) is converted into a spade and another text(“🔴”) into a big red circle using utf-8 encoding scheme.<\/p>\n\n\n\n
Other encoding schemes: <\/strong>Base64, ASCII, URL Encoding, etc<\/p>\n\n\n\nWhat is Encryption?<\/h2>\n\n\n\n
Encryption is the process of taking a message and scrambling its content so that only authorized people can access it.<\/p>\n\n\n\n
Encryption service<\/a> protects sensitive data, both online (bank details, emails, social networks) and offline (stored on hard drives), ensuring only authorized access.<\/p>\n\n\n\nBy using encryption techniques we can enhance our security by preventing attacks like identity theft, and eavesdropping and can maintain confidentiality throughout the communication. <\/p>\n\n\n\n
Although there are many encryption systems, the most common ones are the use of public and private keys.<\/p>\n\n\n\n
Let’s talk about the types of encryption:<\/strong><\/h3>\n\n\n\n1. Symmetric key encryption:<\/h4>\n\n\n\n
This technique of encryption involves only one secret key to encrypt and decrypt the information. <\/p>\n\n\n\n
Both sender and recipient must know the secret key, making symmetric encryption faster, but it requires secure key storage and a safe channel for key transfer.<\/p>\n\n\n\n![\"encryption\"](\"https:\/\/cloudkul.com\/blog\/wp-content\/uploads\/2021\/07\/encryption.png\")
<\/a><\/figure>\n\n\n\nSome widely used<\/strong> Symmetric<\/strong> cryptographic<\/strong><\/strong> algorithms are – <\/strong>AES-128, AES-256, DES-3, and BLOWFISH.<\/p>\n\n\n\n2. Asymmetric key encryption:<\/h4>\n\n\n\n
This technique uses two keys: a private key and a public key, where the private key will be a secret key and the public key will be a public key.<\/p>\n\n\n\n
For instance: you share your public key with the public so that anyone who wants to send you a message can encrypt the message using your public key and send it to you. <\/p>\n\n\n\n
Now as only you have access to your private key, only you can decrypt the message.<\/p>\n\n\n
\n![\"asymmetric\"](\"https:\/\/cloudkul.com\/blog\/wp-content\/uploads\/2021\/07\/assysmtric-1024x371.png\")
<\/a><\/figure><\/div>\n\n\nSome widely used Asymmetric<\/strong><\/strong> cryptographic<\/strong><\/strong> algorithms are –<\/strong> RSA, DSA, Elliptic curve techniques, and PKCS.<\/p>\n\n\n\nWhat is Obfuscation?<\/h2>\n\n\n\n
Obfuscation is the practice of making something difficult to read and understand. <\/p>\n\n\n\n
Generally, software\u2019s code is obfuscated to protect developers\/company intellectual property from being copied, to avoid tempering, and to defend code from attackers.<\/p>\n\n\n\n
How it works:<\/strong><\/h3>\n\n\n\nIt may involve the encryption of code, stripping out potentially revealing metadata, renaming important class names, and variables, and adding null bytes, and meaningless code. <\/p>\n\n\n\n
Some other techniques like the use of Packers, crypters, or Exclusive or Operation are common practices.<\/p>\n\n\n
\n![\"works\"](\"https:\/\/cloudkul.com\/blog\/wp-content\/uploads\/2021\/07\/obfuscation.png\")
<\/a><\/figure><\/div>\n\n\nWhat is Tokenization?<\/h2>\n\n\n\n
Tokenization is a way of protecting sensitive information by replacing it with an algorithmically generated secure random token.<\/p>\n\n\n\n
Tokenization replaces sensitive cardholder details with a token to avoid leaking banking sensitive information over the internet during transactions.<\/p>\n\n\n\n
Tokenized data is irreversible and can not be predictable, as there is no relationship between the token and the original data. <\/p>\n\n\n\n
Therefore, even if information is leaked, attackers will not be able to use it.<\/p>\n\n\n\n![\"Tokenization\"](\"https:\/\/cloudkul.com\/blog\/wp-content\/uploads\/2021\/07\/tokenization.png\")
<\/a><\/figure>\n\n\n\nWe can achieve Detokenization through the original tokenization system. There is no way to obtain original data from just a token.<\/p>\n\n\n\n
So far we have discussed different techniques and where to use them to achieve our goal of secure communication over the Internet.<\/p>\n\n\n\n
