zip flag 1 代表的是ZIP文件的加密标志。这意味着该ZIP文件使用了某种形式的加密来保护其内容,防止未经授权的访问。 错误原因: 用户遇到的错误 unzip: zip flag 1 (encryption) is not supported 表明当前使用的 unzip 工具不支持解压加密的ZIP文件。这通常是因为unzip工具的版本不支持ZIP文件中使用的加密方法。
generalPurposeBitFlag can be found on an Entry or LocalFileHeader. Only General Purpose Bit 11 is used, and only when an Info-ZIP Unicode Path Extra Field cannot be found in extraFields. fileNameBuffer is a Buffer representing the file name field of the entry. This is entry.fileNameRaw ...
ISO character encodings other than Latin-1 are not supported. The new addition of (partially) Unicode (resp. UTF-8) support in UnZip 6.0 has not yet been adapted to the encryption password handling in unzip. On systems that use UTF-8 as native character encoding, unzip simply tries ...

Encrypted archives are fully supported by Info-ZIP software, but due to United States export restrictions, de-/encryption support might be disabled in your compiled binary. However, since spring 2000, US export restrictions have been liberated, and our source archives do now include full crypt cod...

Therefore, compressed size and compression ratio figures are independent of the entry's encryption status and show the correct compres- sion performance. (The complete size of the encrypted compressed data stream for zipfile entries is reported by the more verbose zipinfo(1L) reports, see the ...
