The CSP is always responsible for the secure storage of private keys. Optionally the CSP may assume responsibility for the secure storage of other object types, such as symmetric keys and certificates. The implementation of secured persistent storage for keys can use the services of a Data Storage Library module within the CSSM framework (if that module provides secured storage) or some approach internal to the CSP. Accessing persistent objects managed by the CSP, other than keys, is performed using CSSM's Data Storage Library APIs.
CSPs optionally support a password-based login sequence. When login is supported, the caller is allowed to change passwords as deemed necessary. This is part of a standard user-initiated maintenance procedure. Some CSPs support operations for privileged, CSP administrators. The model for CSP administration varies widely among CSP implementations. For this reason, CSSM does not define APIs for vendor-specific CSP administration operations. CSP vendors can make these services available to CSP administration tools using the CSSM_Passthrough function.
The range and types of cryptographic services a CSP supports is at the discretion of the vendor. A registry and query mechanism is available through the CSSM for CSPs to disclose the services and details about the services. As an example, a CSP may register with the CSSM: Encryption is supported, the algorithms present are DES with cipher block chaining for key sizes 40 and 56 bits, triple DES with 3 keys for key size 168 bits.
All cryptographic services requested by applications will be channeled to one of the CSPs via the CSSM. CSP vendors only need target their modules to CSSM for all security-conscious applications to have access to their product.
Calls made to a Cryptographic Service Provider (CSP) to perform cryptographic operations occur within a framework called a session, which is established and terminated by the application. The session context (simply referred to as the context) is created prior to starting CSP operations and is deleted as soon as possible upon completion of the operation. Context information is not persistent; it is not saved permanently in a file or database.
Before an application calls a CSP to perform a cryptographic operation, the application uses the query services function to determine what CSPs are installed, and what services they provide. Based on this information, the application then can determine which CSP to use for subsequent operations; the application creates a session with this CSP and performs the operation.
Depending on the class of cryptographic operations, individualized attributes are available for the cryptographic context. Besides specifying an algorithm when creating the context, the application may also initialize a session key, pass an initialization vector and/or pass padding information to complete the description of the session. A successful return value from the create function indicates the desired CSP is available. Functions are also provided to manage the created context.
When a context is no longer required, the application calls CSSMDeleteContext. Resources that were allocated for that context can be reclaimed by the operating system.
Cryptographic operations come in two types-a single call to perform an operation and a staged method of performing the operation. For the single call method, only one call is needed to obtain the result. For the staged method, there is an initialization call followed by one or more update calls, and ending with a completion (final) call. The result is available after the final function completes its execution for most cryptographic operations-staged encryption/decryption are an exception in that each update call generates a portion of the result.
The two PKI-based algorithms with wide spread usage are:
For RSA-based algorithms, CDSA adopts the PKCS#1 standard for key representation.
For DSA-based algorithms, no organization has published a standard and no de facto standard seems to exists. CDSA defines a standard representation for DSA key based on the DSA algorithm definitions in the FIPS 186 and FIPS 186a standards. Complete documentation on these standards can be found at http://csrc.ncsl.nist.gov/fips/fips186.txt and at http://csrc.ncsl.nist.gov/fips/fips186a.txt respectively.
A DSA public key is represented as a BER-encoded, ordered sequence containing the prime modulus, the prime divisor, the order modulo the prime modulus, and the public key value. A DSA private key is represented as a BER-encoded, ordered sequence containing the prime modulus, the prime divisor, the order modulo the prime modulus, and the private key value. Additional information is provided in the specification titled CSSM Cryptographic Service Providers Interface.
