Decrypt a short message with a private key. Opcode: 11 (0x000B)


key_nameStringName of the key to use for the operation
algAsymmetricEncryptionAn asymmetric encryption algorithm that is compatible with the type of key
ciphertextVector of bytesShort message to decrypt
saltVector of bytesSalt to use during encryption, if supported by the algorithm
  • key_name must be the name of an RSA asymmetric key pair. The key must allow the usage flag decrypt.
  • salt can be provided if supported by the algorithm. If the algorithm does not support salt, pass an empty vector. If the algorithm supports optional salt, pass an empty vector to indicate no salt. For RSA PKCS#1 v1.5 encryption, no salt is supported.


plaintextVector of bytesBuffer containing the decrypted message

Specific response status codes

  • PsaErrorNotPermitted: The key does not have the decrypt flag, or it does not permit the requested algorithm.


This function will decrypt a short message with the private key of the provided key pair.
