Some VeraCrypt volumes can't be unlocked
It was reported that some non-AES encrypted VeraCrypt volumes can't be unlocked: https://mailman.boum.org/pipermail/tails-testers/2018-August/001084.html
I was able to reproduce this. It seems like
cryptsetup does not support the Camellia and Kuznyechik encryption algorithms, as well as the Streebog hash algorithm, which were all added to VeraCrypt in 2016.
I don't think we will be able to fix this, and I don't know if there are any efforts upstream to support those.
All other algorithms currently supported in VeraCrypt are also supported in cryptsetup and Tails 3.9.
