class Digest::SHA1

Overview

Implements the SHA1 digest algorithm.

Warning: SHA1 is no longer a cryptographically secure hash, and should not be used in security-related components, like password hashing. For passwords, see Crypto::Bcrypt::Password. For a generic cryptographic hash, use SHA-256 via OpenSSL::Digest.new("SHA256").

Class Method Detail

def self.base64digest(data) : String #

Returns the base64-encoded hash of data.

require "digest/sha1"

Digest::SHA1.base64digest("foo") # => "C+7Hteo/D9vJXQ3UfzxbwnXaijM="

[View source]
def self.base64digest(& : Digest::Base -> _) : String #

Yields a context object with an #update(data : String | Bytes) method available. Returns the resulting digest in base64 representation afterwards.

require "digest/sha1"

Digest::SHA1.base64digest do |ctx|
  ctx.update "f"
  ctx.update "oo"
end
# => "C+7Hteo/D9vJXQ3UfzxbwnXaijM="

def self.digest(data) #

Returns the hash of data. data must respond to #to_slice.


[View source]
def self.digest(& : Digest::Base -> _) : Bytes #

Yields an instance of self which can receive calls to #update(data : String | Bytes) and returns the finalized digest afterwards.

require "digest/md5"

digest = Digest::MD5.digest do |ctx|
  ctx.update "f"
  ctx.update "oo"
end
digest.to_slice.hexstring # => "acbd18db4cc2f85cedef654fccc4a4d8"

def self.hexdigest(data) : String #

Returns the hexadecimal representation of the hash of data.

require "digest/md5"

Digest::MD5.hexdigest("foo") # => "acbd18db4cc2f85cedef654fccc4a4d8"

[View source]
def self.hexdigest(& : Digest::Base -> _) : String #
