78 \&\fBBIO_f_md()\fR returns the message digest BIO method. This is a filter
79 BIO that digests any data passed through it.  It is a BIO wrapper
83 Any data written or read through a digest BIO using \fBBIO_read_ex()\fR and
90 \&\fBBIO_reset()\fR reinitialises a digest BIO.
92 \&\fBBIO_set_md()\fR sets the message digest of BIO \fBb\fR to \fBmd\fR: this
93 must be called to initialize a digest BIO before any data is
111 After the digest has been retrieved from a digest BIO it must be
117 a buffering BIO.
119 Calling \fBBIO_get_md_ctx()\fR will return the context and initialize the BIO
124 \&\fBBIO_f_md()\fR returns the digest BIO method.
130 The following example creates a BIO chain containing an SHA1 and MD5
131 digest BIO and passes the string "Hello World" through it. Error
