|
|---|
| 10 | #include <openssl/ripemd.h>
|
|---|
| 11 |
|
|---|
| 12 | The following functions have been deprecated since OpenSSL 3.0, and can be
|
|---|
| 13 | hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value,
|
|---|
| 14 | see L<openssl_user_macros(7)>:
|
|---|
| 15 |
|
|---|
| 16 | unsigned char *RIPEMD160(const unsigned char *d, unsigned long n,
|
|---|
| 17 | unsigned char *md);
|
|---|
| 18 |
|
|---|
| 19 | int RIPEMD160_Init(RIPEMD160_CTX *c);
|
|---|
| 20 | int RIPEMD160_Update(RIPEMD160_CTX *c, const void *data, unsigned long len);
|
|---|
| 21 | int RIPEMD160_Final(unsigned char *md, RIPEMD160_CTX *c);

| 23 | =head1 DESCRIPTION
|
|---|
| 24 |
|
|---|
| 25 | All of the functions described on this page are deprecated.
|
|---|
| 26 | Applications should instead use L<EVP_DigestInit_ex(3)>, L<EVP_DigestUpdate(3)>
|
|---|
| 27 | and L<EVP_DigestFinal_ex(3)>.
|
|---|
| 28 |
|
|---|
| 29 | RIPEMD-160 is a cryptographic hash function with a
|
|---|
| 30 | 160 bit output.
|
|---|
| 31 |
|
|---|
| 32 | RIPEMD160() computes the RIPEMD-160 message digest of the B<n>
|
|---|
| 33 | bytes at B<d> and places it in B<md> (which must have space for
|
|---|
| 34 | RIPEMD160_DIGEST_LENGTH == 20 bytes of output). If B<md> is NULL, the digest
|
|---|
| 35 | is placed in a static array.
|
|---|
| 36 |
|
|---|
| 37 | The following functions may be used if the message is not completely
|
|---|
| 38 | stored in memory:
|
|---|
| 39 |
|
|---|
| 40 | RIPEMD160_Init() initializes a B<RIPEMD160_CTX> structure.
|
|---|
| 41 |
|
|---|
| 42 | RIPEMD160_Update() can be called repeatedly with chunks of the message to
|
|---|
| 43 | be hashed (B<len> bytes at B<data>).
|
|---|
| 44 |
|
|---|
| 45 | RIPEMD160_Final() places the message digest in B<md>, which must have
|
|---|
| 46 | space for RIPEMD160_DIGEST_LENGTH == 20 bytes of output, and erases
|
|---|
| 47 | the B<RIPEMD160_CTX>.
|
|---|
| 48 |
|
|---|
| 49 | =head1 RETURN VALUES
|
|---|
| 50 |
|
|---|
| 51 | RIPEMD160() returns a pointer to the hash value.
|
|---|
| 52 |
|
|---|
| 53 | RIPEMD160_Init(), RIPEMD160_Update() and RIPEMD160_Final() return 1 for
|
|---|
| 54 | success, 0 otherwise.
|
|---|
| 55 |
|
|---|
| 56 | =head1 NOTE
|
|---|
| 57 |
|
|---|
| 58 | Applications should use the higher level functions
|
|---|
| 59 | L<EVP_DigestInit(3)> etc. instead of calling these
|
|---|
| 60 | functions directly.
