Appendix A. ASN.1 Syntax

This section defines ASN.1 syntax for the key derivation functions, the encryption schemes, the message authentication scheme, and supporting techniques. The intended application of these definitions includes PKCS #8 and other syntax for key management, encrypted data, and integrity-protected data. (Various aspects of ASN.1 are specified in several ISO/IEC standards [ISO8824-1] [ISO8824-2] [ISO8824-3] [ISO8824-4].)

The object identifier pkcs-5 identifies the arc of the OID tree from which the OIDs (specific to PKCS #5) in this section are derived:

rsadsi OBJECT IDENTIFIER ::= {iso(1) member-body(2) us(840) 113549}
pkcs OBJECT IDENTIFIER   ::= {rsadsi 1}
pkcs-5 OBJECT IDENTIFIER ::= {pkcs 5}
