4.2 Encryption Algorithms, Modes, and Parameters
For use in conjunction with this RFC, RFC 1423 defines the
appropriate algorithms, modes, and associated identifiers to be used
for encryption of message text with DEKs.
The mechanisms defined in this RFC incorporate facilities for
transmission of cryptographic parameters (e.g., pseudorandom
Initializing Vectors (IVs)) with PEM messages to which the
confidentiality service is applied, when required by symmetric
message encryption algorithms and modes specified in RFC 1423.
Certain operations require encryption of DEKs, MICs, and digital
signatures under an IK for purposes of transmission. A header
facility indicates the mode in which the IK is used for encryption.
RFC 1423 specifies encryption algorithm and mode identifiers and
minimum essential support requirements for key encryption processing.
RFC 1422 specifies asymmetric, certificate-based key management
procedures based on CCITT Recommendation X.509 to support the message
processing procedures defined in this document. Support for the key
management approach defined in RFC 1422 is strongly recommended. The
message processing procedures can also be used with symmetric key
management, given prior distribution of suitable symmetric IKs, but
no current RFCs specify key distribution procedures for such IKs.
