Can buffers in openssl’s RSA_private_decrypt/RSA_public_encrypt overlap?
By buffers i mean second and third args – unsigned char *from, unsigned char *to.
This is not documented. However, OpenSSL itself uses
RSA_private_decrypt()with the same pointer forfromandto, inssl/s3_srvr.c(seen in OpenSSL 0.9.8o source code), so it must be safe.
