Hi,
I'm new to OpenSSL, having just installed openssl-fips-1.2. I'm looking
for some guidance in how to use OpenSSL (from the command line) to
verify ECDSA signatures.
In particular, I have the following questions:
* is it possible to define our own curves (rather than using

Hello,
Using the OpenSSL command line, is it possible to compute hashes of data
which is not a whole number of bytes in length? For example, a block of
data consisting of (say) 110 bits?
Padding the data is not an option, because we need to be able to verify
hashes which have been computed

if you want to play with your EC, check crypto/ec/ectest.c if you want
to add a new curve to openssl, have a look at crypto/ec/ec_curve.c,
crypto
- is there an extra 'not' in this statement?),
but that perhaps doesn't cover ECDSA.

Thank you, Emanuele.

Hi,
To generate an HMAC key using SHA-256, I can issue the following
command:
openssl dgst -sha256 -hmac key -binary message.bin mac.bin
I realised (eventually!) that the key is not supplied as a hex string
(0a0b34e5.. etc.) but in a binary format. Obviously this leads to some

looming ever closer.
Thanks,

I seem to have some success if I place quotes around the [Linux]
command
line:
$ cat message.bin | openssl dgst -sha256 -hmac `cat key.bin` -binary

(Don't need cat here, just on the openssl
