AESCBC Cipher

Represents an Advanced Encryption Standard Cipher Block Chaining (AES CBC) cipher. The object properties are:

PropertyRequired/OptionalDescription
typerequiredMust be set to "aescbc".
keyrequiredThe cipher key as a string, either 128, 192 or 256 bits represented as 16, 24 or 32 hexadecimal bytes.
initialisation vectorrequiredThe initialisation vector as a string, 128 bits represented as 16 hexadecimal bytes.

  • Examples:


    •     {
             "type" : "aescbc",
             "key" : "431F43FAF57534C91F2DEB2E502A4C8CBA58AB5018BD1506419EEA86DF595D3A",
             "initialisation_vector" : "F846443B9B85FAED9AB17570D5A82A31"
      	}
      
  • AesCbcCipher Class
    Namespace: Aculab.Cloud.RestAPIWrapper
    Assembly: Aculab.Cloud.RestAPIWrapper.dll

    A class that represents the Advanced Encryption Standard (AES) cipher in Cipher Block Chaining (CBC) mode. The block size for this cipher is 128 bits.

    public class AesCbcCipher : Cipher
    {
        // Constructors
        public AesCbcCipher(byte[] key, byte[] initialisationVector);
    
        // Members
        public byte[] InitialisationVector;
    }
