There is EVP_PKEY_get_size() function which will give you the maximum
length the encrypted data can have. Unfortunately it cannot give you
the exact length which might be smaller in some cases.

The SSL BIO should have the rbio from the SSL object as the next BIO.
If you create the SSL BIO and then BIO_push() the TCP socket BIO into
the SSL BIO, it will work correctly.
Otherwise, you can just fix the next BIO of the SSL BIO by using
BIO_up_ref(socketbio);
BIO_set_next(sslbio, socketbio);
Hi,
unfortunately I do not see anything wrong with the code. Does the
EVP_DigestVerifyFinal return 0 or negative value? I do not think this
is a bug in OpenSSL as this API is thoroughly tested and it is highly
improbable that there would be a bug in the ECDSA verification through
this API.

Hi,
Here is question,can you help me out? Thanks.
Background:
I am working to write an openssl engine to use cryptographic algorithm in a
hardware device. The hardware device support asymmetric/symmetric algorithm,
for example:rsa/aes.

When I write openssl engine, I shall use ENGIN
Hello Cyprus,
I’m not exactly what you’d call an expert on openssl, but I do use it
frequently. There is a very good openssl wrapper project called EasyRSA that I
highly recommend. We put together a very simple Certificate Authority for
application testing using this package and it made thing
I have an application that constructs a chain of BIOs. Sometimes this
chain also includes an SSL BIO. Years ago, I ran into a problem that
caused BIO_flush() to segfault on the SSL BIO. This turned out to
happen because the SSL BIO is added using SSL_set_bio() instead of
BIO_push(). SSL_set

Hello Tomas,
So, I made sure that px_size and py_size are equal to the group order (48). I
was able to verify successfully using our previous method (deprecated) with the
new key generation method, but I'm still not able to get the digestverify to
work success
Hello

the Intermediate CA due to its role as both a requester and a provider o
