• Android Platform:

  Does not require any additional steps.

Usage

Import the library

import RNEncryptionModule from "@dhairyasharma/react-native-encryption";

Encrypt Text

RNEncryptionModule.encryptText(
    plainText,
    password
    ).then((res: any) => {
        if (res.status == "success") {
            console.log("success", res)
        } else {
            Alert.alert("Error", res);
        }
        }).catch((err: any) => {
            console.log(err);
        });

• plainText : Plain text to be encrypted.
• password : Password to encrypt the plain text.

returns

// If text encryption is successful, it returns a JSON object with the following structure:
{
  "status": "success",
  "encryptedText": "encryptedText",
  "iv": "iv",
  "salt": "salt"
}

or

// If text encryption is unsuccessful, it returns a JSON object with the following structure:
{
  "status": "Fail",
  "error": "error"
}

Decrypt Text

RNEncryptionModule.decryptText(
    encryptedText,
    password,
    iv,
    salt).then((res: any) => {
        if (res.status == "success") {
            console.log("success", res)
        } else {
            Alert.alert("Error", res);
        }
        }).catch((err: any) => {
            console.log(err);
        });

• encryptedText : Cipher text to be decrypted.
• password : Password to decrypt the cipher text.
• iv : Initialization vector from encryptText.
• salt : Salt from encryptText.

returns

// If text decryption is successful, it returns a JSON object with the following structure:
{
  "status": "success",
  "decryptedText": "decryptedText"
}

or

// If text decryption is unsuccessful, it returns a JSON object with the following structure:
{
  "status": "Fail",
  "error": "error"
}

Encrypt File

 RNEncryptionModule.encryptFile(
      inputFilePath,
      outputEncryptedFilePath,
      password
    ).then((res: any) => {
        if (res.status == "success") {
            console.log("success", res)
        } else {
            console.log("error", res);
        }
        }).catch((err: any) => {
            console.log(err);
        });

• inputFilePath : Path of the file to be encrypted.
• outputEncryptedFilePath : Path of the encrypted file.
• password : Password to encrypt the file.

returns

// If file encryption is successful, it returns a JSON object with the following structure:
{
  "status": "success",
  "iv": "iv",
  "salt": "salt"

}

or

// If file encryption is unsuccessful, it returns a JSON object with the following structure:
{
  "status": "Fail",
  "error": "error"
}

Decrypt File

 RNEncryptionModule.decryptFile(
      encryptedFilePath,
      outputDecryptedFilePath,
      password,
      iv,
      salt
    ).then((res: any) => {
        if (res.status == "success") {
            console.log("success", res)
        } else {
            console.log("error", res);
        }
        }).catch((err: any) => {
            console.log(err);
        });

• encryptedFilePath : Path of the file to be decrypted.
• outputDecryptedFilePath : Path of the decrypted file.
• password : Password to decrypt the file.
• iv : Initialization vector from encryptFile.
• salt : Salt from encryptFile.

returns

// If file decryption is successful, it returns a JSON object with the following structure:
{
  "status": "success",
  "message" : "File decrypted successfully"

}

or

// If file decryption is unsuccessful, it returns a JSON object with the following structure:
{
  "status": "Fail",
  "error": "error"
}

NOTE

On android, Input or Output file path does not support content://  type file path. Please use file://  type file path.

You can use react-native-fetch-blob stat to get original path. See example.

You will need Files and media permission for this.
