2.3.4.7 ECMA-376 Document Encryption Key Generation (Standard Encryption)
2.3.4.11 Encryption Key Generation (Agile Encryption)
The encryption key for ECMA-376 document encryption [ECMA-376] using agile encryption MUST be
generated by using the following method, which is derived from PKCS #5: Password-Based
Cryptography Version 2.0 [RFC2898].
