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}
