These 5 lines of code will run every night (you do nightly builds, right?) for the next year or more and will be worth the effort if even just once it happens...

Do you (really) write exception safe code? [closed]
...ding Herb Sutter's Guru Of The Week series, in particular installments 59, 60 and 61.
To summarize, there are three levels of exception safety you can provide:

Type 6: unofficial idea for sequential UUIDs
An SHA1 hash outputs 160 bits (20 bytes); the result of the hash is converted into a UUID.
With the 20-byte hash from SHA1:
SHA1 Digest: 74738ff5 5367 e958 9aee 98fffdcd1876 94028007
