- Method Detail
  - getCipherAlgorithmName
```
String getCipherAlgorithmName()
```
    Returns:
    
    the algorithm name of created ciphers (ie: AES, CAST5, ...)
  - getIVSize
```
int getIVSize()
```
    Returns:
    
    the cipher block size (in bytes) that should be used to generate an IV or -1 if the cipher does not use an initialization vector.
  - getKeySize
```
int getKeySize()
```
    Returns:
    
    the recommended default key size of created ciphers (in bytes), usually the largest one supported.
  - getSupportedKeySizes
```
int[] getSupportedKeySizes()
```
    Returns:
    
    an array of the supported key sizes of created ciphers (in bytes).
  - isSupportedKeySize
```
boolean isSupportedKeySize(int keySize)
```
    Parameters:
    
    keySize - the size in bytes of a proposed key.
    
    Returns:
    
    true if the proposed key size is supported.
