.. 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. \*(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<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "EVP_RC2_CBC 3ossl" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
EVP_rc2_cbc, EVP_rc2_cfb, EVP_rc2_cfb64, EVP_rc2_ecb, EVP_rc2_ofb, EVP_rc2_40_cbc, EVP_rc2_64_cbc \- EVP RC2 cipher Header "SYNOPSIS" .Vb 1 #include <openssl/evp.h> \& const EVP_CIPHER *EVP_rc2_cbc(void); const EVP_CIPHER *EVP_rc2_cfb(void); const EVP_CIPHER *EVP_rc2_cfb64(void); const EVP_CIPHER *EVP_rc2_ecb(void); const EVP_CIPHER *EVP_rc2_ofb(void); const EVP_CIPHER *EVP_rc2_40_cbc(void); const EVP_CIPHER *EVP_rc2_64_cbc(void); .Ve Header "DESCRIPTION" The \s-1RC2\s0 encryption algorithm for \s-1EVP.\s0 Item "EVP_rc2_cbc(), EVP_rc2_cfb(), EVP_rc2_cfb64(), EVP_rc2_ecb(), EVP_rc2_ofb()" \s-1RC2\s0 encryption algorithm in \s-1CBC, CFB, ECB\s0 and \s-1OFB\s0 modes respectively. This is a variable key length cipher with an additional parameter called \*(L"effective key bits\*(R" or \*(L"effective key length\*(R". By default both are set to 128 bits. Item "EVP_rc2_40_cbc(), EVP_rc2_64_cbc()" \s-1RC2\s0 algorithm in \s-1CBC\s0 mode with a default key length and effective key length of 40 and 64 bits. .Sp \s-1WARNING:\s0 these functions are obsolete. Their usage should be replaced with the \fBEVP_rc2_cbc(), EVP_CIPHER_CTX_set_key_length() and EVP_CIPHER_CTX_ctrl() functions to set the key length and effective key length. Header "NOTES" Developers should be aware of the negative performance implications of calling these functions multiple times and should consider using \fBEVP_CIPHER_fetch\|(3) instead. See \*(L"Performance\*(R" in crypto\|(7) for further information. Header "RETURN VALUES" These functions return an \s-1EVP_CIPHER\s0 structure that contains the implementation of the symmetric cipher. See EVP_CIPHER_meth_new\|(3) for details of the \s-1EVP_CIPHER\s0 structure.
