appended to it.

-If @file{SRC} equals to @file{-}, then create an encrypted temporary
-file and copy everything taken from @code{stdin} to it and use for outbound
-packet creation. Pay attention that if you want to send 1 GiB of data
-taken from @code{stdin}, then you have to have more than 2 GiB of disk space
-for that temporary file and resulting encrypted packet. You can control
-temporary file location directory with @env{$TMPDIR} environment
-variable. Encryption is performed in AEAD mode with

-algorithms. Data is divided on 128 KiB blocks. Each block is encrypted
-with increasing nonce counter. File is deletes immediately after
-creation, so even if program crashes -- disk space will be reclaimed, no
-need in cleaning it up later.
