base64.b32decode() now raises a binascii.Error when the input string contains non-b32-alphabet characters, instead of a TypeError. This particular TypeError was missed when the other TypeErrors were converted. (Contributed by Serhiy Storchaka in bpo-18011.) Note: this change was also inadverte...

简单替换密码的密钥很容易出错,因为它们相当长,需要包含字母表中的每个字母。例如,很容易输入缺少一个字母的密钥或两次输入相同字母的密钥。keyIsValid()函数确保密钥可被加密和解密函数使用,如果密钥无效,该函数将退出程序并显示一条错误消息: 代码语言:javascript 代码运行次数:0 运行 复制 if keyIsValid(myKey): ...

Inside rotate_chr(), you first check if the character is in the alphabet. If not, then you return the same character. This has the purpose of keeping punctuation marks and other unusual characters. In line 8, you calculate the new rotated position of the character in the alphabet. To ...
