An issue with passwords was found with a version of the Blowfish algorithm developed for John the Ripper.Here is a list of BCrypt-related security issues/concerns that have come up over the years. We will spend some time ensuring that this library is as secure as possible. If you find or suspect an issue with the code, please bring it to the maintainers' attention. a UTF-8 encoded string containing emojis).Īs should be the case with any security tool, anyone using this library should scrutinise it. It is possible for a string to contain less than 72 characters, while taking up more than 72 bytes (e.g. Note that this is not the first 72 characters. Any extra bytes are ignored when matching passwords. Per bcrypt implementation, only the first 72 bytes of a string are used. If you do not, you'll likely see an error that starts with: gyp ERR! stack Error: "pre" versions of node cannot be installed, use the -nodedir flag instead Since the bcrypt module uses node-gyp to build and install, you'll need a stable version of node to use bcrypt. Node-gyp only works with stable/released versions of node. #HASHTAB INSTALL GUIDE UPGRADE#Please upgrade to atleast v5.0.0 to avoid security issues mentioned below. However, it must provide enough information so the problem can be replicable, or it may be closed without an explanation. The code snippet does not require you to include confidential information. If you are on a stable version of NodeJS, please provide a sufficient code snippet or log files for installation issues.
