| 58 | .In openssl/bio.h | ||
| 59 | .Sh DESCRIPTION | ||
| 60 | A BIO is an I/O abstraction, | ||
| 61 | hiding many of the underlying I/O details from an application. | ||
| 62 | If an application uses a BIO for its I/O, it can transparently handle | ||
| 63 | SSL connections, unencrypted network connections and file I/O. | ||
| 64 | .Pp | ||
| 65 | There are two types of BIO, a source/sink BIO and a filter BIO. | ||
| 66 | .Pp | ||
| 67 | As its name implies, a source/sink BIO is a source and/or sink of data. | ||
| 68 | Examples include a socket BIO and a file BIO. | ||
| 69 | .Pp | ||
| 70 | A filter BIO takes data from one BIO and passes it through | ||
| 71 | to another, or to the application. | ||
| 72 | The data may be left unmodified (for example a message digest BIO) | ||
| 73 | or translated (for example an encryption BIO). | ||
| 74 | The effect of a filter BIO may change according to the I/O operation | ||
| 75 | it is performing: for example an encryption BIO will encrypt data | ||
| 76 | if it is being written to and decrypt data if it is being read from. | ||
| 77 | .Pp | ||
| 78 | BIOs can be joined together to form a chain | ||
| 79 | (a single BIO is a chain with one component). | ||
| 80 | A chain normally consist of one source/sink BIO | ||
| 81 | and one or more filter BIOs. | ||
| 82 | Data read from or written to the first BIO then traverses the chain | ||
| 83 | to the end (normally a source/sink BIO). | ||
