Decrypt error when using openssl 1.1.1b during SSL handshake

[Mahendra SP]

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.
Decryption of pre-master secret is done using hardware and is successful.
We compared the pre-master secret on both server and client and they match.
However, we see that SSL handshake fails with "decrypt error (51)" with an
alert number 21. Verifying the encrypted finish message on the server side
fails.

This issue does not happen with software performing RSA private key
operations.

Can someone help with the reason for decryption failure? Below is the
compiler and processor details. It is 64 bit.
arm-linux-gnueabihf-gcc  -march=armv7ve -mthumb -mfpu=neon -mfloat-abi=hard

Thanks
Mahendra
