List of generateDerivedParameters() Examples

Examples of generateDerivedParameters()

org.bouncycastle.crypto.PBEParametersGenerator.generateDerivedParameters()
generate derived parameters for a key of length keySize. @param keySize the length, in bits, of the key required. @return a parameters object representing a key.
org.bouncycastle.crypto.generators.OpenSSLPBEParametersGenerator.generateDerivedParameters()
Generate a key parameter derived from the password, salt, and iteration count we are currently initialised with. @param keySize the size of the key we want (in bits) @return a KeyParameter object. @exception IllegalArgumentException if the key length larger than the base hash size.
org.bouncycastle.crypto.generators.PKCS12ParametersGenerator.generateDerivedParameters()
Generate a key parameter derived from the password, salt, and iteration count we are currently initialised with. @param keySize the size of the key we want (in bits) @return a KeyParameter object.
org.bouncycastle.crypto.generators.PKCS5S2ParametersGenerator.generateDerivedParameters()
Generate a key parameter derived from the password, salt, and iteration count we are currently initialised with. @param keySize the size of the key we want (in bits) @return a KeyParameter object.
org.bouncycastle2.crypto.PBEParametersGenerator.generateDerivedParameters()
generate derived parameters for a key of length keySize. @param keySize the length, in bits, of the key required. @return a parameters object representing a key.
org.bouncycastle2.crypto.generators.OpenSSLPBEParametersGenerator.generateDerivedParameters()
Generate a key parameter derived from the password, salt, and iteration count we are currently initialised with. @param keySize the size of the key we want (in bits) @return a KeyParameter object. @exception IllegalArgumentException if the key length larger than the base hash size.
