| ) |
Read a buffer for PEM information and store the resulting data into the specified context buffers.
- Parameters:
-
ctx context to use header header string to seek and expect footer footer string to seek and expect data source data to look in (must be nul-terminated) pwd password for decryption (can be NULL) pwdlen length of password use_len destination for total length used (set after header is correctly read, so unless you get MBEDTLS_ERR_PEM_BAD_INPUT_DATA or MBEDTLS_ERR_PEM_NO_HEADER_FOOTER_PRESENT, use_len is the length to skip)
- Note:
- Attempts to check password correctness by verifying if the decrypted text starts with an ASN.1 sequence of appropriate length
- Returns:
- 0 on success, or a specific PEM error code

| ) |
Write a buffer of PEM information from a DER encoded buffer.
- Parameters:
-
header header string to write footer footer string to write der_data DER data to write der_len length of the DER data buf buffer to write to buf_len length of output buffer olen total length written / required (if buf_len is not enough)
- Returns:
- 0 on success, or a specific PEM or BASE64 error code. On MBEDTLS_ERR_BASE64_BUFFER_TOO_SMALL olen is the required size.
