File::KDBX::IO::HashBlock - Hash block stream IO handle
version 0.906
Writing to a hash-block handle will transform the data into a series of blocks. Each block is hashed, and the hash is included with the block in the stream.
Reading from a handle, each hash block will be verified as the blocks are disassembled back into a data stream.
This format helps ensure data integrity of KDBX3 files.
Each block is encoded thusly:
Block index - Little-endian unsigned 32-bit integer, increments starting with 0
Hash - 32 bytes
Block size - Little-endian unsigned 32-bit (counting only the data)
Data - String of bytes
The terminating block is an empty block where hash is 32 null bytes, block size is 0 and there is no data.
Digest algorithm in hash-blocking the stream (default: SHA-256)
SHA-256
Desired block size when writing (default: $File::KDBX::IO::HashBlock::BLOCK_SIZE or 1,048,576 bytes)
$File::KDBX::IO::HashBlock::BLOCK_SIZE
$fh = File::KDBX::IO::HashBlock->new(%attributes); $fh = File::KDBX::IO::HashBlock->new($fh, %attributes);
Construct a new hash-block stream IO handle.
