Precautions
• The certificate may not be generated depending on the total length of data entered in "Subject" (excluding "Country").
The maximum allowed data length varies depending on the RSA encryption key length.
UTF-8 encoding applies to "Subject". The following table lists the maximum allowed data lengths.
RSA encryption key length
1024 bits
2048 bits
In UTF-8 encoding, an ASCII character occupies one byte. However, a Japanese or other character that belongs to the
Unicode basic multilingual plane occupies three bytes.
• When a new client certificate is generated, the validity period begins one day before the creation date.
• When a certificate is generated while the module is communicating, the communication speed may decrease. Also,
certificate generation may take time.
