RSA_public_encrypt(3) -- RSA public key cryptography
|
|
RSA_public_encrypt() encrypts the flen bytes at from (usually a session key) using the public key rsa and stores the ciphertext in to. to must point to RSA_size(rsa) bytes of memory. padding denotes o... |
|
RSA_set_method(3) -- select RSA method
|
|
An RSA_METHOD specifies the functions that OpenSSL uses for RSA operations. By modifying the method, alternative implementations such as hardware accelerators may be used. Initially, the default is to... |

RSA_sign(3) -- RSA signatures
|
|
RSA_sign() signs the message digest m of size m_len using the private key rsa as specified in PKCS #1 v2.0. It stores the signature in sigret and the signature size in siglen. sigret must point to RSA... |
|
RSA_sign_ASN1_OCTET_STRING(3) -- RSA signatures
|
|
RSA_sign_ASN1_OCTET_STRING() signs the octet string m of size m_len using the private key rsa represented in DER using PKCS #1 padding. It stores the signature in sigret and the signature size in sigl... |
|
RSA_size(3) -- get RSA modulus size
|
|
This function returns the RSA modulus size in bytes. It can be used to determine how much memory must be allocated for an RSA encrypted value. rsa->n must not be NULL. |
|
ruserok(3) -- routines for returning a stream to a remote command
|
|
The rcmd() function is available for use by anyone to run commands on a remote system. It acts like the orcmd() command, with the exception that it makes a call out to the rcmd(1) command, or any othe... |
|
scalb(3) -- IEEE test functions
|
|
These functions allow users to test conformance to IEEE Std 754-1985. Their use is not otherwise recommended. logb(x) returns x's exponent n, a signed integer converted to double-precision floating-p... |

|
scalbn(3) -- Functions for IEEE arithmetic
|
|
These functions are required or recommended by IEEE Std 754-1985. copysign() returns x with its sign changed to y's. finite() returns the value 1 just when -infinity < x < +infinity; otherwise a zero... |

|
scandir(3) -- scan a directory
|
|
The scandir() function reads the directory dirname and builds an array of pointers to directory entries using malloc(3). It returns the number of entries in the array. A pointer to the array of direct... |
|
scanf(3) -- input format conversion
|
|
The scanf() family of functions scans input according to a format as described below. This format may contain conversion specifiers; the results from such conversions, if any, are stored through the p... |
|
secure_path(3) -- determine if a file appears to be ``secure''
|
|
The secure_path() function takes a path name and returns zero if the referenced file is ``secure'', non-zero if not. Any ``insecurity'', other than failure to access the referenced file, will be l... |
|
seed48(3) -- pseudo random number generators and initialization routines
|
|
The rand48() family of functions generates pseudo-random numbers using a linear congruential algorithm working on integers 48 bits in size. The particular formula employed is r(n+1) = (a * r(n) + c) m... |
|
seekdir(3) -- directory operations
|
|
The opendir() function opens the directory named by filename, associates a directory stream with it and returns a pointer to be used to identify the directory stream in subsequent operations. The poin... |
