Results for: "pstore"

Returns the memory address for this handle.

Or read the memory at address address with length len and return a string with that memory

Get the free function for this pointer.

Returns a new instance of Fiddle::Function.

See Fiddle::Function.new

Set the free function for this pointer to function in the given Fiddle::Function.

Returns if the free function for this pointer has been called.

Returns the integer memory location of this pointer.

without 0

Returns a new Fiddle::Pointer instance that is a reference pointer for this pointer.

Analogous to the ampersand operator in C.

Return the object that this pinned instance references.

Returns true if the reference has been cleared, otherwise returns false.

Wakes up all threads waiting for this lock.

Returns the string representation of the bignum.

BN.new can parse the encoded string to convert back into an OpenSSL::BN.

base

The format. Must be one of the following:

• 0 - MPI format. See the man page BN_bn2mpi(3) for details.

• 2 - Variable-length and big-endian binary encoding. The sign of the bignum is ignored.

• 10 - Decimal number representation, with a leading ‘-’ for a negative bignum.

• 16 - Hexadecimal number representation, with a leading ‘-’ for a negative bignum.

Fully resets the internal state of the Cipher. By using this, the same Cipher instance may be used several times for encryption or decryption tasks.

Internally calls EVP_CipherInit_ex(ctx, NULL, NULL, NULL, NULL, -1).

Return the hash value computed with name Digest. name is either the long name or short name of a supported digest algorithm.

Example

OpenSSL::Digest.digest("SHA256", "abc")

Returns the names of all available digests in an array.

Resets the Digest in the sense that any Digest#update that has been performed is abandoned and the Digest is set to its initial state again.

Returns the authentication code an a Base64-encoded string.

Returns the authentication code as a binary string. The digest parameter specifies the digest algorithm to use. This may be a String representing the algorithm name or an instance of OpenSSL::Digest.

Example

key = 'key'
data = 'The quick brown fox jumps over the lazy dog'

hmac = OpenSSL::HMAC.digest('SHA1', key, data)
#=> "\xDE|\x9B\x85\xB8\xB7\x8A\xA6\xBC\x8Az6\xF7\n\x90p\x1C\x9D\xB4\xD9"

Returns the authentication code as a hex-encoded string. The digest parameter specifies the digest algorithm to use. This may be a String representing the algorithm name or an instance of OpenSSL::Digest.

Example

key = 'key'
data = 'The quick brown fox jumps over the lazy dog'

hmac = OpenSSL::HMAC.hexdigest('SHA1', key, data)
#=> "de7c9b85b8b78aa6bc8a7a36f70a90701c9db4d9"

Returns the authentication code as a Base64-encoded string. The digest parameter specifies the digest algorithm to use. This may be a String representing the algorithm name or an instance of OpenSSL::Digest.

Example

key = 'key'
data = 'The quick brown fox jumps over the lazy dog'

hmac = OpenSSL::HMAC.base64digest('SHA1', key, data)
#=> "3nybhbi3iqa8ino29wqQcBydtNk="

Returns hmac as it was when it was first initialized, with all processed data cleared from it.

Example

data = "The quick brown fox jumps over the lazy dog"
instance = OpenSSL::HMAC.new('key', 'SHA1')
#=> f42bb0eeb018ebbd4597ae7213711ec60760843f

instance.update(data)
#=> de7c9b85b8b78aa6bc8a7a36f70a90701c9db4d9
instance.reset
#=> f42bb0eeb018ebbd4597ae7213711ec60760843f
