Hi All,
We have crypto engines for offloading operations like RSA, digests and
ciphers, hmac etc. We are looking at a way to load and unload engines at
run time. This is needed as we need to use the engine when needed for
crypto operations. Else we plan to use openssl for the same.
We tried,

Hi All,
Can you please let me know any inputs on the above query?

Hi All,
We are using the openssl 1.1.1 version and using the ENGINE implementation
for some crypto operation. Engine gets loaded dynamically and initialized
successfully and we are able to use the engine.
However, we plan to stop using this engine from the application side once
we are done with it
Hi All,
We are planning to use our own RAND implementation using an engine. What we
observe is, during Openssl init, default RAND gets initialized to openssl
RAND.
Then later we initialize our engine RAND. Even though we make our RAND as
default, we see that still openssl uses the initial default
sue in hardware and return the correct data.
Please suggest if you have any comments for the above info.
Thanks

Hi All.
We have upgraded openssl version to 1.1.1b
With this, we are seeing decryption error during SSL handshake for the
below explained scenario. Our device acts as an SSL server.
We have external hardware to offload RSA private key operations using the
engine.

Hi All,
While writing the engine implementation for private key encryption and
decryption, I need to get the private key from external source.
ENGINE_set_load_privkey_function(e, load_tpm_private_key)
Above API is success.
RSA structure is as below.
RSA_METHOD my_rsa_struct =
{
"MY RSA method"
Hi,
We are looking at implementing an engine for RSA and AES.
For AES, looking at the documentation, understand that engine will get
invoked only if the application or SSL library invokes EVP based calls
rather than native AES calls. Is this correct ?
For RSA, is it mandatory to use EVP for usin
Hi Matt,
Thank you for the inputs.
I have one more query. Is it appropriate to check for the errno in this
case and take action based on the errno values ?
Thanks

Hi All,
We are using Openssl version 1.0.2h. When we call SSL_do_handshake,
sometimes we notice that handshake fails with error SSL_ERROR_SSL.
As per the documentation for this error, it is non recoverable and fatal
error. Documentation also mentions to check the error queue for further
details.
Hi All,
I am seeing an issue with the routine CRYPTO_cbc128_encrypt() in version
1.0.2h where,
, if I have not declared STRICT_ALIGNMENT, application crashes
intermittently.
There was a similar query here but for CRYPTO_ctr128_encrypt.
