Disable any 96-bit HMAC Algorithms
Received a vulnerability - SSH INSECURE HMAC ALGORITHMS ENABLED.
The solution was to Disable any 96-bit HMAC Algorithms. Disable any MD5-based HMAC Algorithms.
Can someone please tell me how to disable in AIX 5.3?
Thanks,
Sudo

Hi,
Hi I have setup Websphere Portal and Apache server on Solaris.
The problem is that clients are allowed to negotiate lower encryption levels and by default the Websphere Apache HTTP server accepts 56-bit keys (your Firefox client requested 256-bit AES below).

CCHMAC(3) BSD Library Functions Manual CCHMAC(3)
NAME
CCHmacInit, CCHmacUpdate, CCHmacFinal, CCHmac -- Common HMAC Algorithm Interfaces
LIBRARY
These functions are found in libSystem.
SYNOPSIS
#include <CommonCrypto/CommonHMAC.h>
void
CCHmacInit(CCHmacContext *ctx, CCHmacAlgorithm algorithm, const void *key, size_t keyLength);
void
CCHmacUpdate(CCHmacContext *ctx, const void *data, size_t dataLength);
void
CCHmacFinal(CCHmacContext *ctx, void *macOut);
void
CCHmac(CCHmacAlgorithm algorithm, const void *key, size_t keyLength, const void *data, size_t dataLength, void *macOut);
DESCRIPTION
This interface provides access to a number of HMAC algorithms. The following algorithms are available:
kCCHmacAlgSHA1 - HMAC with SHA1 digest
kCCHmacAlgMD5 - HMAC with MD5 digest
kCCHmacAlgSHA256 - HMAC with SHA256 digest
kCCHmacAlgSHA384 - HMAC with SHA384 digest
kCCHmacAlgSHA224 - HMAC with SHA224 digest
kCCHmacAlgSHA512 - HMAC with SHA512 digest
The object declared in this interface, CCHmacContext, provides a handle for use with the CCHmacInit() CCHmacUpdate() and CCHmacFinal() calls
to complete the HMAC operation. In addition there is a one shot function, CCHmac() that performs a complete HMAC on a single piece of data.
HISTORY
These functions are available in OS X 10.5 and later.
