System Application · System.Security.Encryption · BC24-30 · [source at ea08af5e](https://github.com/microsoft/BCApps/blob/ea08af5ef2d6a9b5c5af4a029288abbe2c883220/src/System%20Application/App/Cryptography%20Management/src/SignatureAlgorithmv2.Interface.al) · facts from BC29

## Procedures

- `GetInstance(var DotNetAsymmetricAlgorithm: DotNet AsymmetricAlgorithm)`
- `FromSecretXmlString(XmlString: SecretText)`
- `SignData(DataInStream: InStream; HashAlgorithm: Enum "Hash Algorithm"; SignatureOutStream: OutStream)`
- `ToSecretXmlString(IncludePrivateParameters: Boolean): SecretText`
- `VerifyData(DataInStream: InStream; HashAlgorithm: Enum "Hash Algorithm"; SignatureInStream: InStream): Boolean`

## Implemented by

- [Codeunit 1446 "RSACryptoServiceProvider Impl."](../codeunit/1446.md)
- [Codeunit 1448 "DSACryptoServiceProvider Impl."](../codeunit/1448.md)
- [Codeunit 1476 "RSA Impl."](../codeunit/1476.md)
- [Enum 1446 "SignatureAlgorithm"](../enum/1446.md)

## Across versions

- Present in: BC24-30
- Changed (declaration) in: none

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: "interface", object_name: "Signature Algorithm v2")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
