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...

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...

Blowfish is an encryption method developed by Bruce Schneier in 1993 as an alternative to the DES encryption method. It is significantly faster than DES and provides good encryption speed, although no effective cryptanalysis technique has been found to date. It is one of the first secure block ciphers that is not protected by any patents and is therefore freely available for anyone to use. This is a symmetric block cipher algorithm. Block size: 64 bits Key size: variable size from 32 to 448 bits number of subsections: 18 [P-array] number of rounds: 16 number of substitution blocks: 4 [each with 512 records of 32 bits each] develop  Example: import java.io.UnsupportedEncodingException import java.nio.charset.Charset import java.security.InvalidKeyException import java.security.NoSuchAlgorithmException import java.util.* import javax.crypto.BadPaddingException import javax.crypto.Cipher import javax.crypto.IllegalBlockSizeException import javax.crypto.NoSuchPaddingException ...
