Returns the base64-encoded hash of data.

require "digest/sha1"

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

def self.base64digest(&) : String #

Returns the base64-encoded hash of data.

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.

def self.digest(&) #

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

def self.hexdigest(&) : String #

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