System Application · System.Security.Encryption · BC23-30 · [source at ea08af5e](https://github.com/microsoft/BCApps/blob/ea08af5ef2d6a9b5c5af4a029288abbe2c883220/src/System%20Application/App/Cryptography%20Management/src/DESCryptoServiceProvider.Codeunit.al) · facts from BC29

## Properties

| Property | Value |
|---|---|
| Access | Public |

## Procedures

- `EncryptText(DecryptedText: Text; Password: SecretText; Salt: Text): Text`: Encrypts text with DotNet Cryptography.DESCryptoServiceProvider
- `DecryptText(EncryptedText: Text; Password: SecretText; Salt: Text): Text`: Decrypts text with DotNet Cryptography.DESCryptoServiceProvider
- `EncryptStream(Password: SecretText; Salt: Text; InputInstream: InStream; var OutputOutstream: OutStream)`: Encrypts data in stream with DotNet Cryptography.DESCryptoServiceProvider
- `DecryptStream(Password: SecretText; Salt: Text; InputInstream: InStream; var OutputOutstream: OutStream)`: Decrypts data in stream with DotNet Cryptography.DESCryptoServiceProvider

## 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 1382 "DESCryptoServiceProvider Impl."](../codeunit/1382.md) (4 calls: `DecryptStream → DecryptStream`, `DecryptText → DecryptText`, `EncryptStream → EncryptStream`, …)

## 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: "DESCryptoServiceProvider")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
