## Properties

| Property | Value |
|---|---|
| Access | Internal |

## Procedures

- `InitializeRSA(KeySize: Integer; IncludePrivateParameters: Boolean; var KeyAsXmlString: Text)`
- `InitializeRSA(KeySize: Integer; IncludePrivateParameters: Boolean; var KeyAsXmlString: SecretText)`
- `InitializeCertificateRequestUsingRSA(SubjectName: Text; HashAlgorithm: Enum "Hash Algorithm"; RSASignaturePaddingMode: Enum "RSA Signature Padding")`
- `AddX509BasicConstraintToCertificateRequest(CertificateAuthority: Boolean; HasPathLengthConstraint: Boolean; PathLengthConstraint: Integer; Critical: Boolean)`
- `AddX509EnhancedKeyUsageToCertificateRequest(OidValues: List of [Text]; Critical: Boolean)`
- `AddX509KeyUsageToCertificateRequest(X509KeyUsageFlags: Integer; Critical: Boolean)`
- `GetX509CertificateRequestExtensionCount(): Integer`
- `CreateSigningRequest(var SigningRequestPemString: Text)`
- `CreateSigningRequest(SigningRequestOutStream: OutStream)`
- `CreateSelfSigned(NotBefore: DateTime; NotAfter: DateTime; X509ContentType: Enum "X509 Content Type"; var CertBase64Value: Text)`

Plus 3 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 4100 "Temp Blob"](../codeunit/4100.md) (2 calls: `CreateSigningRequest → CreateInStream`, `CreateSigningRequest → CreateOutStream`)
- [Codeunit 4110 "Base64 Convert"](../codeunit/4110.md) (1 call: `CreateSigningRequest → ToBase64`)

## Called by

- [Codeunit 1463 "CertificateRequest"](../codeunit/1463.md) (8 calls: `AddX509BasicConstraintToCertificateRequest → AddX509BasicConstraintToCertificateRequest`, `AddX509EnhancedKeyUsageToCertificateRequest → AddX509EnhancedKeyUsageToCertificateRequest`, `AddX509KeyUsageToCertificateRequest → AddX509KeyUsageToCertificateRequest`, …)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC24

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: "CertificateRequest Impl.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
