 3.18. algorithm (string)
 
    Configure hash algorithm used for digest authentication. Possible
-   values are "MD5" or "SHA-256". If left empty MD5 is used. If specified,
-   the specified algorithm is used and is also put in the 'algorithm'
-   field of the challenge header.
-
-   Warning: SHA-256 hash values take twice the space of MD5 hash values.
-   So a buffer overflow might occur if this option is used in combination
-   with another auth_* module that does not allocate at least 65 bytes to
-   store hash values. SHA-256 can safely be used with the module auth_db
-   as it allocates 256 bytes to store HA1 values.
-
-   Example 1.16. use SHA-256 example
+   values are "MD5", "SHA-256" or "SHA-512". If left empty MD5 is used. If
+   specified, the specified algorithm is used and is also put in the
+   'algorithm' field of the challenge header.
+
+   Warning: SHA-256/512 hash values take twice or more the space of MD5
+   hash values. So a buffer overflow might occur if this option is used in
+   combination with another auth_* module that does not allocate at least
+   enough (65 or 129) bytes to store hash values. SHA-256/512 can safely
+   be used with the module auth_db as it allocates 256 bytes to store HA1
+   values.
