2018年8月29日 · ASCII(American Standard Code for Information Interchange，美国信息互换标准代码)是一套基于拉丁字母的字符编码，共收录了 128 个字符，用一个字节就可以存储，它等同于国际标准 ISO/IEC 646。

ASCII85 is a character encoding using 85 ASCII symbols. Popularized by the PDF format, it allows a little lighter encoding than Base64. This encoding is sometimes called Base85 but it is not an arithmetic base change to base 85. How to encrypt using ASCII85 encoding?

Ascii85, also called Base85, is a form of binary-to-text encoding developed by Paul E. Rutter for the btoa utility.

Ascii85, also called Base85, is a form of binary-to-text encoding used to communicate arbitrary binary data over channels that were designed to carry only English language human-readable text.

Ascii85，也称为Base85，是由Paul E. Rutter为btoa实用程序开发的二进制文本编码形式。 通过使用五个ASCII字符来表示四个字节的二进制数据（使编码大小¹/ 4大于原始值，假设每个ASCII字符为8位），它比uuencode或Base64更有效，它使用四个字符来表示三个字节数据的增加（¹/ 3增加，假设每个ASCII字符有8位）。 它的主要现代用途是Adobe的PostScript和可移植文档格式文件格式，以及Git使用的二进制文件的补丁编码。 2025 @ 工具迷 Build with love。

Ascii85 is an encoding scheme that uses 7-bit printable ASCII characters, also known as Base85. Ascii85 divides the data into 4 bytes each and converts them into 5 ASCII characters to represent them. There are many variants of Ascii85, and DenCode supports the following three types of …

In the 7-bit ASCII character set, ASCII code 85 is represented by the character U, also known as the uppercase u.

Base85, also known as ASCII85, is a binary-to-text encoding scheme that encodes binary data into ASCII characters, using a set of 85 printable characters. It is commonly used in applications where a compact representation of binary data is needed, and it is more efficient than Base64 because it produces shorter encoded strings.

和Base64一样，Base85编码的设计目标是对二进制数据可打印的ASCII字符进行编码。 但它使用了更大范围的字符集，所以带来更高的效率 扩展： 在线base16编码解码 在线base32编码解码 在线base58编码解码 在线base62编码解码 在线base64编码解码 在线base64Url编码解码
