H A DBIO_s_mem.pod7 BIO_get_mem_ptr, BIO_new_mem_buf - memory BIO
26 BIO_s_mem() returns the memory BIO method function.
28 A memory BIO is a source/sink BIO which uses memory for its I/O. Data
29 written to a memory BIO is stored in a BUF_MEM structure which is extended
36 call to L<BIO_write(3)> will write a single datagram to the memory BIO. A
51 Any data written to a memory BIO can be recalled by reading from it.
85 of this memory is implied. See notes on BIO_set_close().
107 Writes to memory BIOs will always succeed if memory is available: that is
136 allocated memory.
166 Create a memory BIO and write some data to it:

18 contents of the memory regions pointed to by B<a> and B<b>.
22 CRYPTO_memcmp() returns 0 if the memory regions are equal and nonzero
27 Unlike memcmp(2), this function cannot be used to order the two memory regions
H A DOPENSSL_secure_malloc.pod44 the program's dynamic memory area, where keys and other sensitive
64 CRYPTO_secure_malloc_done() releases the heap and makes the memory unavailable
65 to the process if all secure memory has been freed.

107 and 2 if successful but the heap could not be protected by memory

120 CRYPTO_secure_malloc_done() returns 1 if the secure memory area is released, or 0 if not.

249 The memory-leak checking has been deprecated in OpenSSL 3.0 in favor of
250 clang's memory and leak sanitizer.

H A DSMIME_read_CMS.pod21 If cleartext signing is used then the content is saved in a memory bio which is
61 The use of a memory BIO to hold the signed content limits the size of message
62 which can be processed due to memory restraints: a streaming single pass option

H A DBN_new.pod28 are no longer needed. It erases the memory used by B<a> and sets it
34 overwrites the data before the memory is returned to the system.
H A DDSA_SIG_new.pod22 values are erased before the memory is returned to the system.
30 function transfers the memory management of the values to the DSA_SIG object,
H A DOPENSSL_instrument_bus.pod5 OPENSSL_instrument_bus, OPENSSL_instrument_bus2 - instrument references to memory bus
16 It was empirically found that timings of references to primary memory
H A DBUF_MEM_new.pod27 various purposes in the library, most notably memory BIOs.
44 or additionally-allocated memory to zero.
H A Dd2i_PKCS8PrivateKey_bio.pod45 work directly on memory: this can be readily worked around by converting the buffers
46 to memory BIOs, see L<BIO_s_mem(3)> for details.
H A DSRP_user_pwd_new.pod41 owns the original memory.
48 The memory is not freed by SRP_user_pwd_free(), the caller must make sure it is

H A DEVP_KDF-ARGON2.pod13 derivation function, as described in IETF RFC 9106. It is memory-hard in
16 systems that lack large amounts of main memory (such as GPUs or ASICs)
19 Argon2d (Argon2i) uses data-dependent (data-independent) memory access and

71 IOCP, it proves that a memory BIO can be used to support IOCP-based usage.
