class Gem::Package::DigestIO
IO
wrapper that creates digests of contents written to the IO
it wraps.
Attributes
Collected digests for wrapped writes.
{ 'SHA1' => #<OpenSSL::Digest: [...]>, 'SHA512' => #<OpenSSL::Digest: [...]>, }

Wraps io
and updates digest for each of the digest algorithms in the digests
Hash
. Returns the digests hash. Example:
io = StringIO.new digests = { 'SHA1' => OpenSSL::Digest.new('SHA1'), 'SHA512' => OpenSSL::Digest.new('SHA512'), } Gem::Package::DigestIO.wrap io, digests do |digest_io| digest_io.write "hello" end digests['SHA1'].hexdigest #=> "aaf4c61d[...]" digests['SHA512'].hexdigest #=> "9b71d224[...]"
