Overview

Classes for calculating message digests using the SHA-256/384/512 Secure Hash Algorithm(s) by NIST (the US’ National Institute of Standards and Technology), described in FIPS PUB 180-2.

See SHA2.

Class Method Summary

`Class` - Inherited

.base64digest	Returns the base64 encoded hash value of a given string.
.digest	Returns the hash value of a given string.
.file	Creates a digest object and reads a given file, name.
.hexdigest	Returns the hex-encoded hash value of a given string.
.new

Instance Method Summary

`Base` - Inherited

#<<	Update the digest using given string and return `self`.
#block_length	Return the block length of the digest in bytes.
#digest_length	Return the length of the hash value in bytes.
#reset	Reset the digest to its initial state and return `self`.
#update	Alias for Base#<<.
#initialize_copy, #finish

`Instance` - Included

#<<	Updates the digest using a given string and returns self.
#==	If a string is given, checks whether it is equal to the hex-encoded hash value of the digest object.
#base64digest	If none is given, returns the resulting hash value of the digest in a base64 encoded form, keeping the digest’s state.
#base64digest!	Returns the resulting hash value and resets the digest to the initial state.
#block_length	Returns the block length of the digest.
#bubblebabble	Returns the resulting hash value in a Bubblebabble encoded form.
#digest	If none is given, returns the resulting hash value of the digest, keeping the digest’s state.
#digest!	Returns the resulting hash value and resets the digest to the initial state.
#digest_length	Returns the length of the hash value of the digest.
#file	Updates the digest with the contents of a given file name and returns self.
#hexdigest	If none is given, returns the resulting hash value of the digest in a hex-encoded form, keeping the digest’s state.
#hexdigest!	Returns the resulting hash value in a hex-encoded form and resets the digest to the initial state.
#inspect	Creates a printable version of the digest object.
#length	Returns digest_obj.digest_length().
#new	Returns a new, initialized copy of the digest object.
#reset	Resets the digest to the initial state and returns self.
#size	Alias for Instance#length.
#to_s	Returns digest_obj.hexdigest().
#update	Alias for Instance#<<.
#finish	Finishes the digest and returns the resulting hash value.
