🔏 哈希类型识别器（按长度与字符集示意）Hash Identifier (Length and Alphabet Demo)
根据哈希字符串的长度、十六进制/Base64 字符集和常见前缀（$2、argon2 等）猜测可能的算法。仅格式示意，不能验证或破解。本地处理。Guess likely hash algorithms from length, hex/Base64 alphabet and common prefixes ($2, argon2, ...). Format demo only - cannot verify or crack. Processed locally.
使用说明与常见问题How-to & FAQ
「哈希类型识别器（按长度与字符集示意）」是什么？What is the Hash Identifier (Length and Alphabet Demo) tool?
根据哈希字符串的长度、十六进制/Base64 字符集和常见前缀（$2、argon2 等）猜测可能的算法。仅格式示意，不能验证或破解。本地处理。Guess likely hash algorithms from length, hex/Base64 alphabet and common prefixes ($2, argon2, ...). Format demo only - cannot verify or crack. Processed locally.
如何使用「哈希类型识别器（按长度与字符集示意）」？How do I use the Hash Identifier (Length and Alphabet Demo) tool?
在「哈希类型识别器（按长度与字符集示意）」中，先在上方输入或粘贴内容，然后点击「识别」按钮即可。In the Hash Identifier (Length and Alphabet Demo): Type or paste your input above, then click "Identify".
能破解哈希吗？Can this crack a hash?
不能。本页只根据长度和字符猜测可能类型，不做碰撞或预镜像。No. It only guesses type from length and alphabet - no collision or preimage.
为什么同一长度有好几种？Why several algorithms for one length?
例如 32 位十六进制可能是 MD5、MD4 或 NTLM，单靠长度无法区分。For example 32 hex digits may be MD5, MD4 or NTLM - length alone cannot tell them apart.
编码和加密有什么区别？Is encoding the same as encryption?
编码（如 Base64、URL 编码）可直接还原，不提供保密性；加密需要密钥。「哈希类型识别器（按长度与字符集示意）」的处理全部在本地完成。No. Encoding (Base64, URL…) is reversible by anyone; encryption needs a key. The Hash Identifier (Length and Alphabet Demo) works fully offline in your browser.
「哈希类型识别器（按长度与字符集示意）」免费吗？需要注册吗？Is the Hash Identifier (Length and Alphabet Demo) free? Do I need an account?
「哈希类型识别器（按长度与字符集示意）」完全免费，无需注册或安装，打开网页即可使用，手机和电脑都能用；输入的内容只在你的浏览器本地处理。The Hash Identifier (Length and Alphabet Demo) is completely free with no sign-up or install and works on phones and desktops; what you enter is processed only in your browser.
