      "value": "Steeltoe is an open source project that provides a collection of libraries that helps users build cloud-native applications. In Steeltoe.Configuration.Encryption 4.0.0 through 4.1.0, configuring `encrypt:rsa:algorithm=OAEP` does not enable OAEP encryption. Due to an incorrect BouncyCastle transformation string, the `OAEP` setting selects PKCS#1 v1.5, which is the same algorithm as the `DEFAULT` setting. Steeltoe.Configuration.Encryption version 4.2.0 patches the issue."

En Steeltoe.Configuration.Encryption 4.0.0 hasta 4.1.0, configurar “encrypt:rsa:algorithm=OAEP” no habilita el cifrado OAEP. Debido a una cadena de transformación de BouncyCastle incorrecta, la configuración “OAEP” selecciona PKCS#1 v1.5, que es el mismo algoritmo que la configuración “DEFAULT”. Steeltoe.Configuration.Encryption versión 4.2.0 soluciona el problema."
