public EdDSAPrivateKeySpec(byte[] seed,
                           byte[] h,
                           byte[] a,
                           GroupElement A,
                           EdDSAParameterSpec spec)
```
    No validation of any parameters other than a.
    Parameters:
    seed - may be null
    h - may be null
    a - must be "clamped" (for Ed) or reduced mod l (for Red)
    A - if null, will be derived from a.
    Throws:
    IllegalArgumentException - if a not clamped or reduced
  - EdDSAPrivateKeySpec
```
public EdDSAPrivateKeySpec(byte[] seed,
                           EdDSAParameterSpec spec)
```
    Create a new EdDSA private key specification from a seed.
    Parameters:
    seed - the private key
    spec - the parameter specification for this key
    Throws:
    IllegalArgumentException - if seed length is wrong or hash algorithm is unsupported
  - EdDSAPrivateKeySpec
```
public EdDSAPrivateKeySpec(byte[] a,
                           GroupElement A,
                           EdDSAParameterSpec spec)
```
    No validation of any parameters other than a. getSeed() and getH() will return null if this constructor is used.
    Parameters:
    a - must be "clamped" (for Ed) or reduced mod l (for Red)
    A - if null, will be derived from a.
    Throws:
    IllegalArgumentException - if a not clamped or reduced
  - EdDSAPrivateKeySpec
```
public EdDSAPrivateKeySpec(EdDSAParameterSpec spec,
                           byte[] h)
```
    Initialize directly from the hash. getSeed() will return null if this constructor is used.
    Parameters:
    spec - the parameter specification for this key
    h - the private key
    Throws:
    IllegalArgumentException - if hash length is wrong

    Returns:
    the parameter specification
  - getSeed
```
public byte[] getSeed()
```
    Return the seed, or null if constructed from the private key directly.
    Returns:
    will be null if constructed directly from the private key
