了解脱敏规则、支持的数据类型与常见问题。How masking rules work, supported data types, and answers to common questions.
文本脱敏工具会自动识别文本中的手机号、身份证号、银行卡号、邮箱、IP 地址与车牌号,并替换为带星号的脱敏形式,如 138****1234、110***********1234、zh***@example.com。
This tool detects phone numbers, ID card numbers, bank card numbers, emails, IP addresses and license plates, then replaces them with masked forms such as 138****1234, 110***********1234 and zh***@example.com.
全部在浏览器本地完成,原始数据不会上传或存储。
Everything runs locally in your browser - raw data is never uploaded or stored.
手机号保留前 3 后 4;身份证与银行卡保留前后各 3-4 位;邮箱隐藏用户名主体、保留域名;IP 保留前两段。
Phone numbers keep the first 3 and last 4 digits; ID and bank cards keep a few leading and trailing digits; emails hide the username but keep the domain; IPs keep the first two octets.
不能,脱敏用星号替换中间位,原始信息不可还原,适用于安全分享场景。No - the middle characters are replaced and cannot be restored, which is exactly what makes sharing safe.
不会,处理完全在浏览器本地进行,关闭页面即销毁。No - masking happens entirely in your browser and is discarded when you close the page.
脱敏基于格式规则,非标准格式(如短号、座机)可能无法匹配,可在文本中人工调整后重试。Masking relies on format rules; non-standard formats (like short or landline numbers) may not match - adjust the text and retry.
