Expand description

RSA PKCS1 V1.5 padding.

em - The padded message.
em_len - Length of * em - .
m - The message to be padded.
m_len - Length of * m - . 0 <= * m_len - <= * em_len - - 11.
seed - The random seed to be used for the padding.
s_len - Length of * seed - . * s_len - >= * em_len - - 3 - * m_len -

Returns -1 If the message is too long ( * m_len - > * em_len - - 11). Returns -2 If the seed is too short ( * s_len - < * em_len - - 3 - * m_len) - . Returns 0 On success.

@remark The * seed - should consist of non-zero random bytes.
