Bitcoin Explorer

WARNING USE OF THIS SOFTWARE WILL RESULT IN YOUR FUNDS BEING STOLEN

WARNING: The use of this library to generate seeds, contrary to the author's own following suggestions that include no warnings whatsoever, WILL RESULT IN YOUR FUNDS BEING STOLEN as per:

CVE-2023-39910 aka Milksad archive here: Milksad Archive

WARNING: The author is taking zero responsibility for participating in the use of his code in critical reference materials and has taken to blaming the people who used his code to create seeds as per his own examples, in spite of this code being used widely in many non-wallet programs, examples, a widely-read book, and in suggestions in many places on Reddit.

For reference, the following is instructive:

• git commit where the author wrote vulnerable RNG code without any warnings and described it as "optimal"
• Additional write-up by Greg Maxwell describing some of the extent of the damage done

WARNING: The following is being left as-is for historical reference.
