hi!
while i was testing encoding options of openssl i found this parameter list
options are
-in <file> input file
-out <file> output file
-pass <arg> pass phrase source
-e encrypt
-d decrypt
-a/-base64 base64 encode/decode, depending on encryption flag
-k passphrase is the next argument
-kfile passphrase is the first line of the file argument
-md the next argument is the md to use to create a key
from a passphrase. One of md2, md5, sha or sha1
-K/-iv key/iv in hex is the next argument
-[pP] print the iv/key (then exit if -P)
-bufsize <n> buffer size
-engine e use engine e, possibly a hardware device.
Cipher Types
(...)
every option is documented in the manual and on the openssl site, but
i couldn't find any explanation of the -md parameter!
i included it on some commands but i did not notice any differences on
the file output
i taking a (wild) guess saying that adds entropy to the key generated
form the password...
do you know what this option is for and why it isn't documented?
thanks a lot!
Vittorio
