Method Details

getBouncyCastleProvider

Provider getBouncyCastleProvider()

Returns:

BouncyCastle security provider. Can be either non-FIPS or FIPS based provider

getAlgorithmProvider

<T> T getAlgorithmProvider(Class<T> clazz,
 String algorithm)

Get some algorithm provider implementation. Returned implementation can be dependent according to if we have non-fips bouncycastle or fips bouncycastle on the classpath.

Parameters:

clazz - Returned class.

algorithm - Type of the algorithm, which we want to return

Returns:

getCertificateUtils

CertificateUtilsProvider getCertificateUtils()

Get CertificateUtils implementation. Returned implementation can be dependent according to if we have non-fips bouncycastle or fips bouncycastle on the classpath.

Returns:

getPemUtils

PemUtilsProvider getPemUtils()

Get PEMUtils implementation. Returned implementation can be dependent according to if we have non-fips bouncycastle or fips bouncycastle on the classpath.

Returns:

getOCSPProver

<T> T getOCSPProver(Class<T> clazz)

getIdentityExtractorProvider

UserIdentityExtractorProvider getIdentityExtractorProvider()

getEcdsaCryptoProvider

ECDSACryptoProvider getEcdsaCryptoProvider()
