Arguments

  • password - string or array of bytes

  • callback

Returns a promise, which when successful, resolves with an object containing the following properties

  • encryptedSecretKey - array of bytes
  • salt - 32 random bytes
  • nonce - 24 random bytes
  • logN
  • blockSize

decryptEncryptedSecretKey (password, encryptedSecretKeyBundle)

Arguments

  • password - string or array of bytes
  • encryptedSecretKeyBundle - an object with parameters { encryptedSecretKey, salt, nonce, logN, blockSize }
