Configures whether to enable custom cryptographic algorithms for the Authentication plugin. When enabled (not by default) the Security Plugins will enable additional digital signature and key establishment algorithms that are not part of the DDS Security specification (EDDSA+ED25519+SHA512, EDDSA+ED448+SHAKE256, ECDHE-CEUM+X25519, ECDHE-CEUM+X448). Currently only supported in combination with OpenSSL: this property will have no effect when used in combination with wolfSSL.

Possible values

TRUE
FALSE
YES
NO

Description

Configures whether to set custom crypto library (e.g., OpenSSL) allocators. When enabled (not the default) the Security Plugins will configure custom allocator functions (alloc, realloc, free) to the loaded crypto library with the goal of reducing memory fragmentation at the cost of a minimum performance impact. This is currently only supported in combination with OpenSSL. This property is only effective the first time a DomainParticipant loads the Security Plugins within the same process: subsequent DomainParticipant creations will ignore this property and leave the existing configuration unchanged. Moreover, this property is only effective if no allocation has been done with the crypto library builtin allocators before the Security Plugins have been loaded, otherwise a warning will be logged and no change will be made. Important: since the allocator functions live within the Security Plugins library, your application must not make any calls to the crypto library once the Security Plugins have been unloaded from memory.

Description

Controls the number of key revisions that are used to encode samples in the DataWriters’ queues. Must be 0 or between 7 and 1000000. If 0, then key revisions are disabled. A greater key_revision_max_history_depth will further delay the need to reencode writer queue historical samples as new key revisions are generated, but it will increase the memory footprint of the DomainParticipant. The memory used for this is preallocated, and it is roughly equal to 36 bytes (or 164 bytes if the DomainParticipant has at least one DataWriter using ODBC writer history) multiplied by the key_revision_max_history_depth. If there is at least one reliable DataWriter that is protecting its payload, then the DomainParticipant will send 7 key revisions instead of just 1 to each late joiner DomainParticipant. Each key revision adds about 128 bytes of network traffic, so that’s 128 * (7 - 1) = 768 more bytes per late joiner DomainParticipant.
