gnutls_cipher_get_block_size - Linux
Overview
gnutls_cipher_get_block_size retrieves the block size of a cipher algorithm. Block size refers to the number of bytes processed by the cipher at once. This information is crucial for understanding how the cipher operates and can be used for optimization purposes.
Syntax
gnutls_cipher_get_block_size(cipher: Cipher) -> int
| Argument | Description |
|—|—|
| cipher | The cipher for which to retrieve the block size. |
Options/Flags
None.
Examples
To obtain the block size of the AES-256 cipher, use:
block_size = gnutls_cipher_get_block_size(gnutls_cipher_aes_256)
Common Issues
None.
Integration
gnutls_cipher_get_block_size can be used in conjunction with other GNUTLS functions to implement cryptographic algorithms. For instance, it can be used to determine the number of bytes that should be encrypted or decrypted at a time.
