!!! [Netscape Certificate Sequence]
[Netscape Certificate Sequence] is another [PKCS7] object format, and like the SignedData format, it allows multiple [certificates] to be imported together. This format is simpler than the [PKCS7] SignedData object format. It consists of a [PKCS7] ContentInfo structure, wrapping a sequence of certificates. 

The contentType field OID must be netscape-cert-sequence. The content field is the following ASN.1 structure:
{{{
   CertificateSequence ::= SEQUENCE OF Certificate
}}}

The base of all Netscape object ids is:
{{{
   netscape OBJECT IDENTIFIER ::= { 2 16 840 1 113730 }
}}}   
The hexadecimal byte value of this OID when DER encoded is:
{{{
   0x60, 0x86, 0x48, 0x01, 0x86, 0xf8, 0x42
}}}
