Openssl Asn1parse无法正确提取数据

如何解决Openssl Asn1parse无法正确提取数据

使用asn1parse解码openssl数据时出现问题。使用asn1parse命令后，out.pem contains与预期输出不匹配。实际和预期输出均显示如下。 请帮助我解决这个问题。

openssl asn1parse-通知PEM -in base64.pem -out out.pem

解决方法

您的输入文件包含一个长的base64行。 OpenSSL期望base64格式的输入的行以64个字符换行。

如果您处于* nix环境中，则可以使用fold工具进行换行。您可以使用换行来创建输入文件的其他版本，也可以使用Process Substitution一次完成该操作，如下所示：

$ openssl asn1parse -in <(fold -w 64 base64.pem)
    0:d=0  hl=4 l= 921 cons: SEQUENCE          
    4:d=1  hl=2 l=  11 prim: OBJECT            :1.2.840.113549.1.9.16.1.43
   17:d=1  hl=4 l= 904 cons: cont [ 0 ]        
   21:d=2  hl=4 l= 900 prim: OCTET STRING      :{
