Constructor Detail

TlsPrfParameterSpec

public TlsPrfParameterSpec(javax.crypto.SecretKey secret,
                           java.lang.String label,
                           byte[] seed,
                           int outputLength,
                           java.lang.String prfHashAlg,
                           int prfHashLength,
                           int prfBlockSize)

Deprecated.

Constructs a new TlsPrfParameterSpec.

Parameters:

secret - the secret to use in the calculation (or null)

label - the label to use in the calculation

seed - the random seed to use in the calculation

outputLength - the length in bytes of the output key to be produced

prfHashAlg - the name of the TLS PRF hash algorithm to use. Used only for TLS 1.2+. TLS1.1 and earlier use a fixed PRF.

prfHashLength - the output length of the TLS PRF hash algorithm. Used only for TLS 1.2+.

prfBlockSize - the input block size of the TLS PRF hash algorithm. Used only for TLS 1.2+.

Throws:

java.lang.NullPointerException - if label or seed is null

java.lang.IllegalArgumentException - if outputLength is negative

Method Detail

getSecret

public javax.crypto.SecretKey getSecret()

Deprecated.

Returns the secret to use in the PRF calculation, or null if there is no secret.

Returns:

the secret to use in the PRF calculation, or null if there is no secret.

getLabel

public java.lang.String getLabel()

Deprecated.

Returns the label to use in the PRF calculation.

Returns:

the label to use in the PRF calculation.

getSeed

public byte[] getSeed()

Deprecated.

Returns a copy of the seed to use in the PRF calculation.

Returns:

a copy of the seed to use in the PRF calculation.

getOutputLength

public int getOutputLength()

Deprecated.

Returns the length in bytes of the output key to be produced.

Returns:

the length in bytes of the output key to be produced.

getPRFHashAlg

public java.lang.String getPRFHashAlg()

Deprecated.

Obtains the PRF hash algorithm to use in the PRF calculation.

Returns:

the hash algorithm, or null if no algorithm was specified.

getPRFHashLength

public int getPRFHashLength()

Deprecated.

Obtains the length of PRF hash algorithm. It would have been preferred to use MessageDigest.getDigestLength(), but the API does not require implementations to support the method.

Returns:

the hash algorithm length.

getPRFBlockSize

public int getPRFBlockSize()

Deprecated.

Obtains the length of PRF hash algorithm.

Returns:

the hash algorithm length.
