Hi, first post here and I wonder if anyone with a larger brain than me can
help?

I'm in Windows XP Pro and using DD to image a disk and then pipe to openssl
to encrypt.  I'm using the -pass pass:'anotherpassword' switch to make
decryption by the user as easy as possible.  It looks like this:-

dd if=\\.\PhysicalDrive0 conv=noerror | openssl enc -aes-128-ecb -salt -out
encryptedfile.enc

I enter the passphrase when prompted and verify.

Encryption appears to work and I can see the SALTED line at the start of the
file in a Hexviewer.  

However when I try to decrypt using:-

openssl enc -d -aes-128-ecb -salt -in encryptedfile.enc -out finished.dd

and type in the passphrase..

I get the following:-

bad decrypt
4064:error:00065064:digital envelope routines:EVP_DecryptFinal_ex:bad
decrypt: .\crypto\evp\evp_enc.c:330:

I've seen alot of posts that say the passphrase is wrong however I and a
collegue have tried this 20 or 30 times with phrases from 123 to hello to
more complex.  We havent got it wrong each time!

When I look at the resultant file I can see NTFS at the start of the file
meaning it has sort of worked but when I hash compare the input and output
they are different so something hasnt worked.

I am well and truly stuck!

Thanks in advance

Nick
