Subject: [PATCH 0/2] crypto: ecdh & ecc: Fix private key byte ordering issues
Date: Sun, 14 Apr 2024 20:30:24 -0400 [thread overview]
Message-ID: <20240415003026.2661270-1-stefanb@linux.ibm.com> (raw)
The 1st patch fixes a byte ordering issue where ctx->private_key is
currently passed to ecc_is_key_valid but the key is in reverse byte order.
To solve this issue it introduces the variable 'priv' that is already used
throughout the ecc and ecdh code bases for a private key in proper byte
order and calls the function with 'priv'.
The 2nd patch gets rid of the 'priv' variable wherever it is used to hold
a private key (byte-swapped initialized from ctx->private_key) in proper
byte order and uses ctx->private_key directly that is now initialized in
proper byte order.
Regards,
Stefan
