方法概要

限定符和类型	方法和说明
String	algorithmName() Returns the name of the hash algorithm the HashService should use when computing the Hash, or null if the default algorithm configuration of the HashService should be used.
byte[]	salt() Returns a salt to be used by the IHash during hash computation, or null if no salt is provided as part of the request.
byte[]	source() Returns the source data that will be hashed by a IHash.
int	times() Returns the number of requested hash iterations to be performed when computing the final Hash result.

方法详细资料

source

byte[] source()

Returns the source data that will be hashed by a IHash. For example, this might be a ByteSource representation of a password, or file, etc.

返回:

the source data that will be hashed by a IHash.

salt

byte[] salt()

Returns a salt to be used by the IHash during hash computation, or null if no salt is provided as part of the request. Note that a null value does not necessarily mean a salt won't be used at all - it just means that the request didn't include one. The servicing IHash is free to provide a salting strategy for a request, even if the request did not specify one.

返回:

a salt to be used by the IHash during hash computation, or null if no salt is provided as part of the request.

times

int times()

Returns the number of requested hash iterations to be performed when computing the final Hash result. A non-positive (0 or less) indicates that the HashService's default iteration configuration should be used. A positive value overrides the HashService's configuration for a single request. Note that a HashService is free to ignore this number if it determines the number is not sufficient to meet a desired level of security.

返回:

the number of requested hash iterations to be performed when computing the final Hash result.

algorithmName

String algorithmName()

Returns the name of the hash algorithm the HashService should use when computing the Hash, or null if the default algorithm configuration of the HashService should be used. A non-null value overrides the HashService's configuration for a single request. Note that a HashService is free to ignore this value if it determines that the algorithm is not sufficient to meet a desired level of security.

返回:

the name of the hash algorithm the HashService should use when computing the Hash, or null if the default algorithm configuration of the HashService should be used.
