An instance of OM class DS_C_ALGORITHM_IDENT records the encryption algorithm that an object uses to digitally sign messages, together with the parameters of the algorithm.
An instance of this OM class has the OM attributes of its superclass, OM_C_OBJECT, in addition to the OM attributes listed in the following table.
OM Attributes of DS_C_ALGORITHM_IDENT
| OM Attribute |
Value Syntax |
Value Length | Value Number | Value Initially |
| DS_ALGORITHM | String(OM_S_ OBJECT_ IDENTIFIER_ STRING) |
- | 1 | - |
| DS_ALGORITHM_ PARAMETERS |
any | - | 0 or 1 | - |
This attribute specifies an object identifier that uniquely identifies the algorithm used by some object.
· DS_ALGORITHM_PARAMETERS
This attribute specifies the values of the algorithm's parameters that are used by the object. The syntax of the parameters is determined by each individual algorithm.
