bad decrypt error

[Morris, Aaron W.]

I am trying to decrypt a file that has been decrypted in the des3 format.  The guy says that is was decrypted by some kind of hardware device that they use internally to their company.  It is coming from a mainframe then we are trying to decrypt it on  a hp box.  We have tried to convert it to ascii before he encrypts and we still get the bad decrypt error.  Here is the comnmand+error:  /opt/openssl/bin/openssl des3 -d -in ascrypt.txt -out decrypted.txt -K 12345678
bad decrypt
21296:error:06065064:digital envelope routines:EVP_DecryptFinal:bad decrypt:evp_enc.c:277:

 

Any help would be appreciated.
