Generates a signature on the given message digest using ECDSA.

An ECC parameters object.
An ECC private key object.
The length (in bytes) of the message digest.
The message digest.
The length (in bytes) of sValue.
The 's' component from the signature computation.
The length (in bytes) of rValue.
The 'r' component from the signature computation. This is the x-coordinate of the ephemeral public key.
A global context.
This function assumes that the input is a message digest (of any length); no digest operation will be performed on the input.
The ECC parameter object must have been created with an RNG context.
If the length of s is known, a pointer to a buffer large enough to hold s should be passed in sValue and its length in sLength. This function will copy s into sValue and set the actual length of s in sLength.
If sValue is NULL, this function will set the correct length of s in sLength. If sValue is not NULL but sLength is too small, this function will return an error.
Similarly for r.
s and r will always have the same length.
The length of s or r can also be determined by calling hu_ECCParamsGet() and retrieving the OrdLen argument.
The eccParams object is NULL.
The tag for the params object is not of the expected type.
The privateKey object NULL.
The privateKey object invalid.
The message digest length is invalid.
The message digest is NULL.
The signature component length is NULL.
The signature component length is invalid.
The signature component length is NULL.
The signature component length is invalid.
Memory allocation failure.
Success.
