I used golang to implement file encryption and decryption, but I don’t know how to use nodejs to implement golang’s decryption.
golang code:

package main import ( "bytes" "crypto/aes" "crypto/cipher" "crypto/rand" "io" "io/ioutil" "os" ) func encrypt(aeskey string, filename string) { plaintext, err := ioutil.ReadFile(filename) if err != nil { panic(err.Error()) } // Byte array of the string key := []byte(aeskey) // Create the AES cipher block, err := aes.NewCipher(key) if err != nil { panic(err) } // The IV needs to be unique, but not secure. Therefore it's common to // include it at the beginning of the ciphertext. ciphertext := make([]byte, aes.BlockSize+len(plaintext)) iv := ciphertext[:aes.BlockSize] if _, err := io.ReadFull(rand.Reader, iv); err != nil { panic(err) } stream := cipher.NewCFBEncrypter(block, iv) stream.XORKeyStream(ciphertext[aes.BlockSize:], plaintext) // create a new file for saving the encrypted data. f, err := os.Create(filename + ".aes") if err != nil { panic(err.Error()) } _, err = io.Copy(f, bytes.NewReader(ciphertext)) if err != nil { panic(err.Error()) } } func main() { key := "0123456789123456" encrypt(key, "1.ts") }

How can the files encrypted by the above golang code be parsed using nodejs?

I don’t know how to switch to nodejs. It mainly focuses on a few bytes of golang processing. I wrote this myself, but it was wrong. .

var fs = require('fs'); var crypto = require('crypto'); function decrypt(aseKey, inputFile){ var fileBody = fs.readFileSync(inputFile) var cipher = crypto.createDecipheriv("aes128", Buffer.from(aseKey), fileBody.slice(0,16)) var result = cipher.update(fileBody.slice(16)) fs.writeFileSync(inputFile+".n.ts", result) } decrypt("0123456789123456", "1.ts.aes")

Attached is the golang function to decrypt this file

func decrypt(aesKey string, inputFile string) { ciphertext, err := ioutil.ReadFile(inputFile) if err != nil { panic(err.Error()) } // Key key := []byte(aesKey) // Create the AES cipher block, err := aes.NewCipher(key) if err != nil { panic(err) } // Before even testing the decryption, // if the text is too small, then it is incorrect if len(ciphertext) < aes.BlockSize { panic("Text is too short") } // Get the 16 byte IV iv := ciphertext[:aes.BlockSize] // Remove the IV from the ciphertext ciphertext = ciphertext[aes.BlockSize:] // Return a decrypted stream stream := cipher.NewCFBDecrypter(block, iv) // Decrypt bytes from ciphertext stream.XORKeyStream(ciphertext, ciphertext) // create a new file for saving the encrypted data. f, err := os.Create(inputFile + ".ts") if err != nil { panic(err.Error()) } _, err = io.Copy(f, bytes.NewReader(ciphertext)) if err != nil { panic(err.Error()) } } func main() { key := "0123456789123456" decrypt(key, "1.ts.aes") }
