如何使用「MD2 哈希生成器」？How do I use the MD2 Hash Generator?
在输入框输入文本，下方即显示 32 位十六进制的 MD2 值。例如 "abc" 的 MD2 是 da853b0d3f88d99b30283a69e6ded6bb。Type text and the 32-hex-digit MD2 hash appears below. For example, MD2 of "abc" is da853b0d3f88d99b30283a69e6ded6bb.
MD2 还安全吗？Is MD2 still secure?
不安全。MD2 设计于 1989 年，已发现原像攻击和碰撞问题，速度也很慢，只应在需要兼容旧系统（例如旧版 X.509 证书签名）时使用；新项目请用 SHA-256 或 SHA-3。No. MD2 dates from 1989, has known preimage and collision weaknesses and is slow; use it only for legacy compatibility (such as old X.509 signatures) and prefer SHA-256 or SHA-3 for anything new.
