hmac-bcrypt

hmac-bcrypt 此仓库包含 hmac-bcrypt 密码哈希函数在多种语言中的参考实现。每份参考实现都尽可能尝试对 @epixoip 创建的原始 C 和 Perl 实现进行 1:1 移植，并且各实现之间完全兼容（即，它们生成并校验相同的哈希值）。 接口 每份参考实现都定义了以下两个过程式函数，其伪原型如下： string hmacbcrypthashpassword, settings?, pepper? boolean hmacbcryptverifypassword, expected, pepper?...

CVE-2026-103880

Asymmetric Resource Consumption vulnerability in Apache Directory LDAP API. Storing a password using the bcrypt algorithm with a high force like 30 in a LDAP server that supports this algorithm will cause the server CPU to run for hours checking the credentials. A bounded cost should be enforced...

CVE-2026-103880

The Apache Directory LDAP API is vulnerable to an Asymmetric Resource Consumption (CWE-405) issue. When a server supporting the bcrypt algorithm stores a password with a high cost factor (e.g., 30), the server CPU may run for hours during credential verification, potentially leading to a Denial o...

CVE-2026-17508 Password-based KDF cost parameters honoured unbounded from untrusted input across the remaining PBE entry points

In Bouncy Castle for Java before 1.86, several password-based key derivation entry points ran the KDF with cost parameters taken from the untrusted input being processed, without bounding them, so a small input could dictate an arbitrary amount of work before any password or integrity check could...
