OAuth 1.0和1.0a几乎完全相同，但后者修复了一个 安全漏洞——除了网址，OAuth密钥还被用来签署原始域以及请求。

The 1.0 and 1.0a are almost identical, but the latter fixes a security bug which uses the OAuth key to sign the originating domain as well as the request, not just the URL.

在64位的精度下，即使初始密钥中的一个变量有10 - 15的微小差异，密码分析者也根本无法得到原始明文的任何有关信息。

At the precision of 64 bits, even if a variable in the initial key has a minute difference about 10-15, any information about the original plaintext can't be obtained.
