PSA_ALG_IS_STREAM_CIPHER macro
Whether the specified algorithm is a stream cipher. A stream cipher is a symmetric cipher that encrypts or decrypts messages by applying a bitwise-xor with a stream of bytes that is generated from a key.
Syntax
#define PSA_ALG_IS_STREAM_CIPHER(alg) \
(((alg) & (PSA_ALG_CATEGORY_MASK | PSA_ALG_CIPHER_STREAM_FLAG)) == \
(PSA_ALG_CATEGORY_CIPHER | PSA_ALG_CIPHER_STREAM_FLAG))
Return value
1 if \p alg is a stream cipher algorithm, 0 otherwise. This macro may return either 0 or 1 if \p alg is not a supported algorithm identifier or if it is not a symmetric cipher algorithm.
