Encrypting MD entries value

JackTiew · May 13, 2018, 6:52am

I am trying to encrypt the MD entries key or value using window.safeMutableData.encryptKey and window.safeMutableData.encryptValue. However, the result shows:

Is the function being remove from the API?

Encryption of MD keys and values works but you don’t provide enough information to see what is happening there.

You can see working code in the functions getMutableDataValue() and setMutableDataValue() below. There are more examples in that file that might be closer to what you are doing if you search for them.

// Get the key/value of an entry from a mutable data object
//
// Encryption is handled automatically by the DOM APIs
// - if the MD is public, they do nothing
// - if the MD is private, they encrypt/decrypt using the MD private key
//
// @param mdHandle handle of a mutable data, with permission to 'Read'
// @param key the key to read
//
// @returns a Promise which resolves to a ValueVersion
async getMutableDataValue (mdHandle, key) {
  logApi('getMutableDataValue(%s,%s,%s)...', mdHandle, key, isEncrypted)
  let useKey = await window.safeMutableData.encryptKey(mdHandle, key)
  try {
    let valueVersion = await window.safeMutableData.get(mdHandle, useKey)
    valueVersion.buf = window.safeMutableData.decrypt(mdHandle, valueVersion.buf)
    return valueVersion
  } catch (err) {
    logApi("getMutableDataValue() WARNING no entry found for key '%s'", key)
    throw err
  }
