.... Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. | will give a
real vertical bar. \*(C+ will give a nicer C++. Capital omega is used
to do unbreakable dashes and therefore won't be available. \*(C` and
\*(C' expand to `' in nroff, nothing in troff, for use with C<>

If the F register is turned on, we'll generate index entries on stderr
for titles (.TH), headers (.SH), subsections (.Sh), items (.Ip), and
index entries marked with X<> in POD. Of course, you'll have to process
the output yourself in some meaningful fashion.

For nroff, turn off justification. Always turn off hyphenation; it
makes way too many mistakes in technical documents.
Accent mark definitions (@(#)ms.acc 1.5 88/02/08 SMI; from UCB 4.2).
Fear. Run. Save yourself. No user-serviceable parts.

Title "RSA_padding_add_PKCS1_type_1 3"
However, they can also be called directly to implement padding for other asymmetric ciphers. RSA_padding_add_PKCS1_OAEP() and \fIRSA_padding_check_PKCS1_OAEP() may be used in an application combined with \s-1RSA_NO_PADDING\s0 in order to implement \s-1OAEP\s0 with an encoding parameter.
\fIRSA_padding_add_xxx() encodes fl bytes from f so as to fit into \fBtlen bytes and stores the result at to. An error occurs if fl does not meet the size requirements of the encoding method.
The following encoding methods are implemented: p "PKCS1_type_1" 4 Item "PKCS1_type_1" \s-1PKCS\s0 #1 v2.0 EMSA-PKCS1-v1_5 (\s-1PKCS\s0 #1 v1.5 block type 1); used for signatures p "PKCS1_type_2" 4 Item "PKCS1_type_2" \s-1PKCS\s0 #1 v2.0 EME-PKCS1-v1_5 (\s-1PKCS\s0 #1 v1.5 block type 2) p "\s-1PKCS1_OAEP\s0" 4 Item "PKCS1_OAEP" \s-1PKCS\s0 #1 v2.0 \s-1EME-OAEP\s0 p "SSLv23" 4 Item "SSLv23" \s-1PKCS\s0 #1 EME-PKCS1-v1_5 with SSL-specific modification p "none" 4 Item "none" simply copy the data
The random number generator must be seeded prior to calling \fIRSA_padding_add_xxx().
\fIRSA_padding_check_xxx() verifies that the fl bytes at f contain a valid encoding for a rsa_len byte \s-1RSA\s0 key in the respective encoding method and stores the recovered data of at most tlen bytes (for \s-1RSA_NO_PADDING\s0: of size tlen) at to.
For RSA_padding_xxx_OAEP(), p points to the encoding parameter of length pl. p may be \s-1NULL\s0 if pl is 0.
\fIRSA_padding_add_PKCS1_OAEP() and RSA_padding_check_PKCS1_OAEP() were added in OpenSSL 0.9.2b.
