-** PR_GetRandomNoise() -- Get random noise from the host platform |
-** |
-** Description: |
-** PR_GetRandomNoise() provides, depending on platform, a random value. |
-** The length of the random value is dependent on platform and the |
-** platform's ability to provide a random value at that moment. |
-** |
-** The intent of PR_GetRandomNoise() is to provide a "seed" value for a |
-** another random number generator that may be suitable for |
-** cryptographic operations. This implies that the random value |
-** provided may not be, by itself, cryptographically secure. The value |
-** generated by PR_GetRandomNoise() is at best, extremely difficult to |
-** predict and is as non-deterministic as the underlying platfrom can |
-** provide. |
-** |
-** Inputs: |
-** buf -- pointer to a caller supplied buffer to contain the |
-** generated random number. buf must be at least as large as |
-** is specified in the 'size' argument. |
-** |
-** size -- the requested size of the generated random number |
-** |
-** Outputs: |
-** a random number provided in 'buf'. |
-** |
-** Returns: |
-** PRSize value equal to the size of the random number actually |
-** generated, or zero. The generated size may be less than the size |
-** requested. A return value of zero means that PR_GetRandomNoise() is |
-** not implemented on this platform, or there is no available noise |
-** available to be returned at the time of the call. |
-** |
-** Restrictions: |
-** Calls to PR_GetRandomNoise() may use a lot of CPU on some platforms. |
-** Some platforms may block for up to a few seconds while they |
-** accumulate some noise. Busy machines generate lots of noise, but |
-** care is advised when using PR_GetRandomNoise() frequently in your |
-** application. |
-** |
-** History: |
-** Parts of the model dependent implementation for PR_GetRandomNoise() |
-** were taken in whole or part from code previously in Netscape's NSS |
-** component. |
