How do I encrypt a file in react?
To encrypt a file you will need to know its location in the file system. For images you can use React Native API, or a library such as react-native-image-picker or react-native-camera-roll-picker. import { virgilCrypto } from 'react-native-virgil-crypto'; const keypair = virgilCrypto.

NodeJS provides inbuilt library crypto to encrypt and decrypt data in NodeJS. We can use this library to encrypt data of any type. You can do the cryptographic operations on a string, buffer, and even a stream of data. The crypto also holds multiple crypto algorithms for encryption.
- An AES session key is generated along with some encryption parameters.
- Sensitive data are encrypted using the AES key.
- The AES key is encrypted using the recipient's RSA public key.
- The payload is sent with the encrypted session key and parameters.

Encryption uses complex mathematical algorithms and digital keys to encrypt data. An encryption algorithm (cipher) and an encryption key encode data into ciphertext. Once the ciphertext is transmitted to the recipient, the same or different key (cipher) is used to decode the ciphertext back into the original value.

Private keys may be protected with a password, encrypted or hashed for security -- or all three. Key exchange. The private key is used to decrypt, as well as to encrypt, so using it for symmetric encryption requires a key exchange to share that key securely with trusted parties authorized to exchange secured data.
A symmetric key is used during both the encryption and decryption processes. To decrypt a particular piece of ciphertext, the key that was used to encrypt the data must be used. The goal of every encryption algorithm is to make it as difficult as possible to decrypt the generated ciphertext without using the key.
No, not with the current hardware if a good encryption method was used and the key (password) was long enough. Unless there is a flaw in the algorithm and that you know it, your only option is to brute force it which might takes hundred of years.
What is the strongest type of encryption?
AES 256-bit encryption is the strongest and most robust encryption standard that is commercially available today. While it is theoretically true that AES 256-bit encryption is harder to crack than AES 128-bit encryption, AES 128-bit encryption has never been cracked.
There are two types of encryption in widespread use today: symmetric and asymmetric encryption. The name derives from whether or not the same key is used for encryption and decryption.
Encrypted data can be hacked or decrypted with enough time and computing resources, revealing the original content. Hackers prefer to steal encryption keys or intercept data before encryption or after decryption. The most common way to hack encrypted data is to add an encryption layer using an attacker's key.
It would actually be less secure to hash the password and send it over a non-encrypted channel. You will expose your hashing algorithm on the client. Hackers could just sniff the hash of the password and then use it to hack in later.
The result of bcrypt achieves core properties of a secure password function as defined by its designers: It's preimage resistant. The salt space is large enough to mitigate precomputation attacks, such as rainbow tables.
In order to encode/decode a string in JavaScript, We are using built-in functions provided by JavaScript. btoa(): This method encodes a string in base-64 and uses the “A-Z”, “a-z”, “0-9”, “+”, “/” and “=” characters to encode the provided string.
All React developers love to leverage the benefits React caters to in developing web applications. But developers need to keep in mind the security postures while creating React web apps. React applications face a vast attack surface and are prone to different vulnerabilities.

JSX performs optimization while compiling the source code to JavaScript. The generated code runs faster than an equivalent code written directly in JavaScript. The gain may vary, but even the optimized JavaScript libraries like Box2D becomes faster when ported to JSX (12% faster on iOS 5.1, 29% faster on Android 2.3).

- var bytes = CryptoJS.AES.decrypt(ciphertext.toString(), 'secret key 123');
The most common reason for PGP encryption use is to enable people to confidentially send messages and data to each other using a combination of their public and private keys. It is often used to encrypt and decrypt emails, files, text messages, and entire disk partitions, and to authenticate digital certificates.

Out of 128-bit, 192-bit, and 256-bit AES encryption, 256-bit AES encryption is technically the most secure because of its key length size. Some go as far as to label 256-bit AES encryption overkill because it, based on some estimations, would take trillions of years to crack using a brute-force attack.
to call createHash with 'sha256' and call update with the string we want to creatre the has from to create the hash. Then we return the hash digest string from the hash with the digest method. We pass in 'base64' as the argument, so the base64 hash digest is returned.
The AES Encryption algorithm (also known as the Rijndael algorithm) is a symmetric block cipher algorithm with a block/chunk size of 128 bits. It converts these individual blocks using keys of 128, 192, and 256 bits. Once it encrypts these blocks, it joins them together to form the ciphertext.

- use react-native-fs to get the video file base64.
- decrypt it and store it using react-native-fs in DocumentDirectoryPath ( this path is predefined in react-native-fs )
- react-native-video can read base64 file so put the path directly source={{ uri: videoUrl }}
CryptoJS supports AES-128, AES-192, and AES-256. It will pick the variant by the size of the key you pass in. If you use a passphrase, then it will generate a 256-bit key. DES is a previously dominant algorithm for encryption, and was published as an official Federal Information Processing Standard (FIPS).
To encrypt and decrypt data, simply use encrypt() and decrypt() function from an instance of crypto-js. var bytes = CryptoJS. AES. decrypt(ciphertext, 'my-secret-key@123');
How about CryptoJS? It's a solid crypto library, with a lot of functionality. It implements hashers, HMAC, PBKDF2 and ciphers. In this case ciphers is what you need.

- const encryptedMessage = cCryptoGS. CryptoJS. AES.
In cryptography, a salt is random data that is used as an additional input to a one-way function that hashes data, a password or passphrase. Salts are used to safeguard passwords in storage.
AES-128 uses a 128-bit key length to encrypt and decrypt a block of messages. AES-192 uses a 192-bit key length to encrypt and decrypt a block of messages. AES-256 uses a 256-bit key length to encrypt and decrypt a block of messages.
