Thanks for your reply! But it's still not right.
I want to verify the entry in evptest.txt, like the following: # RC4 tests (from rc4test) RC4:0123456789abcdef0123456789abcdef::0123456789abcdef:75b7878099e0c596 I think in this example string "0123456789abcdef0123456789abcdef" is for the key used by rc4, not the password where the key and the iv derived from. And from the man page of enc, we can see that the -k is used for password, the -K is for the key directly used by rc4. But there is no iv in the above entry, however the openssl rc4 need it. so I am confused. Another wonder is that the value for -K is must be hex digits, so we need to hex dump it, The following is steps I tried: echo -n "0123456789abcdef0123456789abcdef" > key.in xxd -r -g0 -p key.in key.out But the content in key.out is not visible, so I also don't know how to specify it in the command line. Can you give me the steps to verify the above RC4 entry? Any help would be appreciated. Thanks in advance!
