Following a recent NPR report that shared security flaws in major email services with Apple, Apple had confirmed that it would soon begin encrypting iCloud emails. Initially Apple only encrypted emails that were sent between its own iCloud customers. With this new change it will encrypt all emails between iCloud and third-party services for me.com and mac.com email addresses.
Apple has not yet spoken about this new change, but we can see this on Google’s transparency website which shows the percentage of iCloud emails that are encrypted in transit for both inbound and outbound email exchanges.
Despite providing a resolution to this security-related issue, there are reports that say Apple’s encryption method might not be as secure as security experts hoped. A report from German website heise.de which examined the new methods of encryption notes that Apple is using the RC4 encryption algorithm. According to the report, RC4 is not as secure as other options that are available.
