The RSA algorithm (Rivest-Shamir-Adleman) is a cryptographic algorithm that is used for specific security services or purposes, which enables public-key encryption and is widely used to secure sensitive data, particularly when it is being sent over an insecure network such as the HTTP. A public key is shared publicly, while a private key is secret and must not be shared with anyone. The following illustration highlights how asymmetric cryptography works: Example 1: RSA Encryption and Decryption with OAEP, package main //Required imports for Encryption & Decryption import ( "crypto/rand" "crypto/rsa" "crypto/sha512" "encoding/base64" "fmt" ) func main() { //3072 is the number of bits for RSA bitSize := 3072 //Generate RSA keys privateKey, err := rsa. GenerateKey(rand.Reader, bitSize) if err != nil { panic(err) } publicKey := privateKey.PublicKey //Your secret te

The cryptographic technique known as Rivest-Shamir-Adleman, or RSA, is used for certain security services or goals. It allows for public-key encryption and is frequently used to protect sensitive data, especially when it's being transferred over an unreliable network like the HTTP. Whereas a private key is confidential and needs to be kept to yourself, a public key is shared with others.   The following illustration highlights how asymmetric cryptography works:   Example:  RSA Encryption and Decryption with RSA-OAEP Padding from Crypto.PublicKey import RSA from Crypto.Cipher import PKCS1_OAEP import base64   # 2048 is the number of bits for RSA keys = RSA.generate( 2048 ) publicKey = keys.publickey() publicKeyPEM = publicKey.exportKey() print( "\n" ,publicKeyPEM.decode( 'ascii' )) privateKeyPEM = keys.exportKey() print( "\n" ,privateKeyPEM.decode( 'ascii' )) # Your secret text secretMessage = 'This is your secret' #encrypt the messag

Advanced Encryption Standard(AES) is a symmetric encryption algorithm. AES encryption is used by the U.S. for securing sensitive but unclassified material, so we can say it is enough secure. It allows 128 bit, 192 bit and 256-bit encryption. Symmetric encryption is very fast as compared to asymmetric encryption and are used in systems such as database system.  The RSA algorithm (Rivest-Shamir-Adleman) is a cryptographic algorithm that is used for specific security services or purposes, which enables public-key encryption and is widely used to secure sensitive data, particularly when it is being sent over an insecure network such as the HTTP. A public key is shared publicly, while a private key is secret and must not be shared with anyone. Encryption's primary purpose is to protect against brute force attacks. It is composed of a cipher, the message/data, and a key (the password). With a wide range of free tools available like(Aircrack-ng, John the Ripper, Rainbow Crack, L0phtCrac

A public key is shared publicly, while a private key is secret and must not be shared with anyone. The following illustration highlights how asymmetric cryptography works: Program to demonstrate RSA encryption and decryption in Node.js, const crypto = require( "crypto" ) // Generating RSA key pairs(public and private key) const { publicKey, privateKey } = crypto.generateKeyPairSync( "rsa" , { // The length of our RSA keys is 3072 bits modulusLength: 3072 , }) //print RSA public key and private key console.log( publicKey.export({ type: "pkcs1" , format: "pem" , }), privateKey.export({ type: "pkcs1" , fo
