Function nrfxlib_sys::ocrypto_rsa_pss_sha256_decode

pub unsafe extern "C" fn ocrypto_rsa_pss_sha256_decode(
    em: *mut u8,
    em_len: usize,
    m: *const u8,
    m_len: usize,
    salt_len: usize
) -> c_int

RSA PSS SHA-256 signature decoding.

• em - The encoded message.
• em_len - Length of * em - .
• m - The signed message.
• m_len - Length of * m - .
• salt_len - The length of the salt.

Returns 0 If the encoding is valid. Returns -1 If decoding failed. Returns -2 If the salt is too long ( * salt_len - > * em_len - - 34).
