| 信息技术 – ASN.1编码规则：基本编码规则（BER）、规范编码规则（CER）和唯一编码规则（DER） |
本建议书 | 国际标准定义了一组基本编码规则（BER），可用于利用ASN.1符号定义的各类数值。这些编码规则的应用产生了用于这些值的传送语法。这些编码规则的规范暗示，它们也会被用于解码。本建议书 | 国际标准还定义了一组区分编码规则（DER）和一套规范编码规则（CER），以便对基本编码规则（BER）加以约束。它们之间的主要区别是，DER使用确定长度的编码形式，而CER使用不确定长度的编码形式。DER是更适合于小的编码数值，而CER更适合大的数值。这一编码规范暗示，它们也被用于解码。 |
