class Digest::SHA1
inherits OpenSSL::Digest
¶
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
Digest::SHA256.
