Examples of %SYSTEM.Encryption class methods

Installation

1. Clone/git pull the repo into any local directory

$ git clone https://github.com/yurimarx/cryptography-samples.git

2. Open a Docker terminal in this directory and run:

$ docker-compose build

3. Run the IRIS container:

$ docker-compose up -d 

4. Open IRIS Terminal:

$ docker-compose exec iris iris session iris -U IRISAPP
IRISAPP>

5. To do RSAEncrypt - for asymmetric encrypt:

IRISAPP>Set ciphertext = ##class(dc.cryptosamples.Samples).DoRSAEncrypt("InterSystems")
IRISAPP>Write ciphertext

6. To do RSADecrypt - for asymmetric decrypt:

IRISAPP>Set plaintext = ##class(dc.cryptosamples.Samples).DoRSADecrypt(ciphertext)
IRISAPP>Write plaintext
InterSystems

7. To do AESCBCEncrypt - for symmetric encrypt:

IRISAPP>Do ##class(dc.cryptosamples.Samples).DoAESCBCEncrypt("InterSystems")

8. To do AESCBCDecrypt - for symmetric decrypt:

IRISAPP>Do ##class(dc.cryptosamples.Samples).DoAESCBCDecrypt("8sGVUikDZaJF+Z9UljFVAA==")
InterSystems

9. To do DoHash - for hash text:

IRISAPP>Do ##class(dc.cryptosamples.Samples).DoHash("InterSystems")
