Plus 5 local procedures.

## Calls

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an `Object::"Name"` argument. Interface dispatch and calls through events are not counted, so the list is not complete.

- [Codeunit 1476 "RSA Impl."](../codeunit/1476.md) (2 calls: `CreateFromPemAndExportAsBase64 → ExportRSAPrivateKeyPem`, `CreateFromPemAndExportAsBase64 → FromSecretXmlString`)

## Called by

- [Codeunit 1286 "X509Certificate2"](../codeunit/1286.md) (16 calls: `CreateFromPemAndExportAsBase64 → CreateFromPemAndExportAsBase64`, `GetCertificateExpiration → GetCertificateExpiration`, `GetCertificateFriendlyName → GetCertificateFriendlyName`, …)
- [Codeunit 1461 "SignedXml Impl."](../codeunit/1461.md) (1 call: `AddKeyInfoClauseFromX509Certificate → InitializeX509Certificate`)
- [Codeunit 1466 "EncryptedXml Impl."](../codeunit/1466.md) (1 call: `Encrypt → InitializeX509Certificate`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC24, BC27-28

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "codeunit", object_name: "X509Certificate2 Impl.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
