[Matroska-devel] Feature Request: MD5 or SHA1 internal checksums

[Jan Fredrik Evensen]

Hi!

I would like to have the possibility to integritycheck the different 
internal parts/streams/subs of the .mkv file to see if the content has not 
been damaged during transfer. This feature would probably only be usable in 
finite files. Maybe some sort of internal database which is included as a 
stream/token inside the .mkv file. This token/stream would contain  the 
md5sums or sha1sums for the other components. This way the codec or an 
external program can verify the internal streams. I do not know if such a 
feature is needed by anyone else.. or if it already has been requested..  :P
