@ -5010,9 +5010,11 @@ Password protected content is encrypted with [AES](https://en.wikipedia.org/wiki
with a 256 bits key derived with [PBKDF2](https://en.wikipedia.org/wiki/PBKDF2) / [SHA](https://en.wikipedia.org/wiki/Secure_Hash_Algorithms)-512 with 120,000 iterations.
With a sufficiently long/complex password, which is communicated to the recipient securely, this is considered safe in 2022 and for the foreseeable future.
Due to [URL](https://en.wikipedia.org/wiki/URL) length limits, the maximum content size is 1,500 bytes,
which includes [HTML](https://en.wikipedia.org/wiki/HTML) formatting tags.
Due to [length limitations](https://stackoverflow.com/a/417184/1794097) of [URL](https://en.wikipedia.org/wiki/URL)s and
Android [binder limitations](https://developer.android.com/reference/android/os/TransactionTooLargeException),
the maximum content size is 1,500 bytes, which includes [HTML](https://en.wikipedia.org/wiki/HTML) formatting tags.
Images will be replaced with placeholders to reduce the content size, but other formatting, like bold, italic, links, etc., will be retained.
If the content is too long, there will be a popup *Text too long*.
The content size limit is also why complete messages (possibly including a long reply chain) cannot be password protected.
You can use [PGP](https://en.wikipedia.org/wiki/Pretty_Good_Privacy) or [S/MIME](https://en.wikipedia.org/wiki/S/MIME) encryption for this (see [this FAQ](#user-content-faq12)).
