+ * There's absolutely no warranty.
+ *
+ * It is my intent that you should be able to use this on your system,

+ * it if you give credit where it is due and keep your modifications in

+ *
+ * This implementation is compatible with OpenBSD bcrypt.c (version 2a)
+ * by Niels Provos <provos at citi.umich.edu>, and uses some of his
+ * ideas. The password hashing algorithm was designed by David Mazieres

+ * There's a paper on the algorithm that explains its design decisions:
+ *
+ * http://www.usenix.org/events/usenix99/provos.html

+ * Some of the tricks in BF_ROUND might be inspired by Eric Young's

+ *
+ * Last synchronized from https://github.com/creachadair/imath/tree/v1.29,
+ * using the following procedure:
+ *
+ * 1. Download imath.c and imath.h of the last synchronized version. Remove
+ * "#ifdef __cplusplus" blocks, which upset pgindent. Run pgindent on the
+ * two files. Filter the two files through "unexpand -t4 --first-only".
+ * Diff the result against the PostgreSQL versions. As of the last
+ * synchronization, changes were as follows:
+ *
+ * - replace malloc(), realloc() and free() with px_ versions
+ * - redirect assert() to Assert()
+ * - #undef MIN, #undef MAX before defining them
+ * - remove includes covered by c.h
+ * - rename DEBUG to IMATH_DEBUG
+ * - replace stdint.h usage with c.h equivalents
+ * - suppress MSVC warning 4146
+ * - add required PG_USED_FOR_ASSERTS_ONLY
+ *
+ * 2. Download a newer imath.c and imath.h. Transform them like in step 1.
+ * Apply to these files the diff you saved in step 1. Look for new lines
+ * requiring the same kind of change, such as new malloc() calls.
+ *
+ * 3. Configure PostgreSQL using --without-openssl. Run "make -C
+ * contrib/pgcrypto check".
+ *
+ * 4. Update this header comment.
