SecureRandomFactoryBean
public SecureRandomFactoryBean()
getObject
public java.security.SecureRandom getObject()
throws java.lang.Exception
- Specified by:
getObject
in interface org.springframework.beans.factory.FactoryBean<java.security.SecureRandom>
- Throws:
java.lang.Exception
getObjectType
public java.lang.Class<java.security.SecureRandom> getObjectType()
- Specified by:
getObjectType
in interface org.springframework.beans.factory.FactoryBean<java.security.SecureRandom>
isSingleton
public boolean isSingleton()
- Specified by:
isSingleton
in interface org.springframework.beans.factory.FactoryBean<java.security.SecureRandom>
setAlgorithm
public void setAlgorithm(java.lang.String algorithm)
- Allows the Pseudo Random Number Generator (PRNG) algorithm to be nominated. Defaults to "SHA1PRNG".
- Parameters:
algorithm
- to use (mandatory)
setSeed
public void setSeed(org.springframework.core.io.Resource seed)
- Allows the user to specify a resource which will act as a seed for the
SecureRandom
instance. Specifically, the resource will be read into an InputStream
and those
bytes presented to the SecureRandom.setSeed(byte[])
method. Note that this will
simply supplement, rather than replace, the existing seed. As such, it is always safe to
set a seed using this method (it never reduces randomness).
- Parameters:
seed
- to use, or null
if no additional seeding is needed
