_computeHash()

void Arcane::SHA1HashAlgorithm::_computeHash ( Span< const std::byte > input, HashAlgorithmValue & value )

private

Definition at line 503 of file SHA1HashAlgorithm.cc.

_computeHash64()

void Arcane::SHA1HashAlgorithm::_computeHash64 ( Span< const std::byte > input, ByteArray & output )

computeHash() [1/2]

void Arcane::SHA1HashAlgorithm::computeHash ( ByteConstArrayView input, ByteArray & output )

overridevirtual

Calculates the hash value for the array input.

The hash value is added to output. The length depends on the algorithm used.

Implements Arcane::IHashAlgorithm.

Here is the call graph for this function:

computeHash() [2/2]

void Arcane::SHA1HashAlgorithm::computeHash ( Span< const std::byte > input, HashAlgorithmValue & value )

overridevirtual

Calculates the hash value for the array input.

The hash value is positioned in value

Reimplemented from Arcane::IHashAlgorithm.

Definition at line 525 of file SHA1HashAlgorithm.cc.

computeHash64() [1/2]

void Arcane::SHA1HashAlgorithm::computeHash64 ( Span< const Byte > input, ByteArray & output )

overridevirtual

Calculates the hash value for the array input.

The hash value is added to output. The added length is equal to hashSize().

Reimplemented from Arcane::IHashAlgorithm.

Here is the call graph for this function:

computeHash64() [2/2]

void Arcane::SHA1HashAlgorithm::computeHash64 ( Span< const std::byte > input, ByteArray & output )

overridevirtual

Calculates the hash value for the array input.

The hash value is added to output. The added length is equal to hashSize().

Definition at line 554 of file SHA1HashAlgorithm.cc.

createContext()

Ref< IHashAlgorithmContext > Arcane::SHA1HashAlgorithm::createContext ( )

overridevirtual

Creates a context to calculate the hash value incrementally.

If the implementation does not support incremental mode (hasCreateContext()==false), an exception is thrown.

Reimplemented from Arcane::IHashAlgorithm.
