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 Summary
-
.base64digest(data) : String
Returns the base64-encoded hash of data.
-
.base64digest(& : Digest::Base -> _) : String
Yields a context object with an
#update(data : String | Bytes)
method available. -
.digest(data)
Returns the hash of data.
-
.digest(& : Digest::Base -> _) : Bytes
Yields an instance of
self
which can receive calls to#update(data : String | Bytes)
and returns the finalized digest afterwards. -
.hexdigest(data) : String
Returns the hexadecimal representation of the hash of data.
-
.hexdigest(& : Digest::Base -> _) : String
Yields a context object with an
#update(data : String | Bytes)
method available.
Instance Method Summary
-
#digest_size : Int32
Returns the digest output size in bytes.
