An ES (JavaScript & TypeScript) module to provide an easier symmetric crypto.

ℹ️ Note

It is possible to use this module in other ways which not listed in here, however it is not officially supported.

@hugoalh/symmetric-crypto

@hugoalh/symmetric-crypto

ℹ️ Note

• Although it is recommended to import the entire module, it is also able to import part of the module with sub path if available, please visit file jsr.jsonc property exports for available sub paths.
• It is recommended to use this module with tag for immutability.

• Via GitHub Raw (Require Tag)

  https://raw.githubusercontent.com/hugoalh-studio/symmetric-crypto-es/${Tag}/mod.ts
  

ℹ️ Note

• Although it is recommended to import the entire module with the main path mod.ts, it is also able to import part of the module with sub path if available, but do not import if:

  • it's file path has an underscore prefix (e.g.: _foo.ts, _util/bar.ts), or
  • it is a benchmark or test file (e.g.: foo.bench.ts, foo.test.ts), or
  • it's symbol has an underscore prefix (e.g.: export function _baz() {}).

  These elements are not considered part of the public API, thus no stability is guaranteed for them.

• Although there have 3rd party services which provide enhanced, equal, or similar methods/ways to remote import the module, beware these services maybe inject unrelated elements and thus affect the security.

This module does not require any permission.

• class SymmetricCryptor {
    decrypt(data: string): Promise<string>;
    decrypt(data: Uint8Array): Promise<Uint8Array>;
    encrypt(data: string): Promise<string>;
    encrypt(data: Uint8Array): Promise<Uint8Array>;
  }

• function createSymmetricCryptor(key: SymmetricCryptorKeyType, times?: number): Promise<SymmetricCryptor>;
  function createSymmetricCryptor(input: SymmetricCryptorKeyInput, times?: number): Promise<SymmetricCryptor>;
  function createSymmetricCryptor(inputs: (SymmetricCryptorKeyInput | SymmetricCryptorKeyType)[]): Promise<SymmetricCryptor>;

• interface SymmetricCryptorKeyInput {

     * Algorithm of the symmetric cryptor.
     * @default "AES-CBC"
     */
    algorithm?: SymmetricCryptorAlgorithmNameType;
    /**
     * Key of the symmetric cryptor.
     */
    key: SymmetricCryptorKeyType;
  }

• type SymmetricCryptorAlgorithmNameType = "AES-CBC" | "AES-CTR" | "AES-GCM";

• type SymmetricCryptorKeyType = string | ArrayBuffer | DataView | Uint8Array | Uint16Array | Uint32Array | BigUint64Array;

• const data = "qwertyuiop";
  const cryptor = await createSymmetricCryptor("<PassWord123456>!!");
  const encrypted = await cryptor.encrypt(data);
  console.log(encrypted);
  // "lST)L-9$J[MPqk)3Pe1qa(;,i)Wi]"4oD9+OE(Hc"
  const decrypted = await cryptor.decrypt(encrypted);
  console.log(decrypted);
  // "qwertyuiop"
