Function nrfxlib_sys::ocrypto_rsa1024_pkcs1_v15_crt_decrypt

pub unsafe extern "C" fn ocrypto_rsa1024_pkcs1_v15_crt_decrypt(
    m: *mut u8,
    m_len: usize,
    c: *const u8,
    sk: *const ocrypto_rsa1024_crt_key
) -> c_int

1024-bit RSA PKCS1 V1.5 decryption with CRT acceleration.

The ciphertext * c - is decrypted to the message returned in * m - .

• m - The decrypted message. The buffer must be long enough to hold the message.
• m_len - Length of * m - .
• c - The 128-byte ciphertext to decrypt.
• sk - A valid 1024-bit RSA secret key with CRT coefficients.

Returns -1 If decryption failed. Returns -2 If the output buffer is too short (m_len < length of message). Returns n If a message of length n was successfully decrypted.

@remark The key * sk - should be initialized with * ocrypto_rsa1024_init_crt_key - . @remark * m - may be same as * c - .
