Hi, fellows. Thanks a lot for the hint. I'm using Blowfish in cfb mode.
Will there be any "padding not removed" problem with this cipher?
Actually I'm very new here. I wonder if anyone can also clarify to me some
basic concepts as well. I really appreciate the help.
1) What is b64-encoding?
2) What is block cipher?
3) In enc manpage, what does a "salt" mean?
4) Suppose I have an input file foo.in and a key file foo.key, and want to
use bf-cfb to encrypt the input file using the key file. What kind of
command should I use?
Specifically, in "openssl bf-cfb -in foo.in -out foo.out", where should I
insert the key file option?

Looks like not removed padding.
Low level crypto functions like (for example) AES_cbc_encrypt()
on encryption add padding but on decryption
you must remove padding yourself.
You should provide more information.
