When I use HMAC-RIPEMD-160, is the size of the header encryption key only 160 bits?
No, VeraCrypt never uses an output of a hash function (nor of a HMAC algorithm) directly as an
encryption key. See the section ‘Header Key Derivation, Salt, and Iteration Count‘ for more
information.
How do I burn a VeraCrypt container larger than 2 GB onto a DVD?
The DVD burning software you use should allow you to select the format of the DVD. If it does,
select the UDF format (ISO format does not support files larger than 2 GB).
Can I use tools like chkdsk, Disk Defragmenter, etc. on the contents of a mounted
VeraCrypt volume?
Yes, VeraCrypt volumes behave like real physical disk devices, so it is possible to use any
filesystem checking/repairing/defragmenting tools on the contents of a mounted VeraCrypt volume.
Does VeraCrypt support 64-bit versions of Windows?
Yes.
Can I mount my VeraCrypt volume under Windows, Mac OS X, and Linux?
Yes, VeraCrypt volumes are fully cross-platform.
Is it possible to install an application to a VeraCrypt volume and run it from there?
Yes.
What will happen when a part of a VeraCrypt volume becomes corrupted?
In encrypted data, one corrupted bit usually corrupts the whole ciphertext block in which it
occurred. The ciphertext block size used by VeraCrypt is 16 bytes (i.e., 128 bits). The mode of
operation used by VeraCrypt ensures that if data corruption occurs within a block, the remaining
blocks are not affected (for more information, see the section Modes of Operation). See also the
question ‘What do I do when the encrypted filesystem on my VeraCrypt volume is corrupted?’
What do I do when the encrypted filesystem on my VeraCrypt volume is corrupted?
File system within a VeraCrypt volume may become corrupted in the same way as any normal
unencrypted file system. When that happens, you can use filesystem repair tools supplied with
your operating system to fix it. In Windows, it is the ‘chkdsk’ tool. VeraCrypt provides an easy way
to use this tool on a VeraCrypt volume: Right-click the mounted volume in the main VeraCrypt
window (in the drive list) and from the context menu select ‘Repair Filesystem’.
